Geographic Information System (GIS) BackgroundCITY OF ROSEMOUNT EXECUTIVE SIIbII+RP,RY FOR ACTION CITY COUNCIL MEETING DATE: October 20, 1992 AGENDA ITEM: Geographic Information Systems AGENDA SECTION: (GIS) Background NEW BUSINESS PREPARED BY: Lisa Freese AGENDA EM „(,�, ,�( fj� 1 A Director of Planning ATTACED1ENTS: Memo; Brochures on GIS Software. ROVE B . The 1990 Capital Improvement Program has $15,000 budgeted for the acquisition of computer hardware and software for a Geographic Information System (GIS). This will enable the City of Rosemount to utilize the automated mapping system that Dakota County is developing with the City's financial assistance. The attached memo provides a background regarding the City's involvement in the development of the Dakota County GIS and the status of the data available to the City. The City had intended to purchase the software for GIS over a year ago, but the change over in staff involved with the project has delayed the acquisition. The delay, however, has worked out to our benefit because the technology has improved and the costs have declined. We have arranged an on-site demonstration of the GIS software. On November 4, 1992, Environmental Systems Research Institute (SSRI) representatives will be conducting a demonstration of the product to City staff at 3:30 in the City Council Chambers. At 5:00 p.m., they will be demonstrating the product for City Council and all Commission members. On Tuesday, I will overview what GIS can do for the City and what our initial capabilities will consist of. RECONIlUMED ACTION: A MOTION to authorize staff to proceed with the selection of GIS software/hardware and obtain quotes from vendors.

McMenomy City Council Members Klassen, Staats, Willcox, and Wippermann FROM: Lisa Freese, Director of Planning DATE: October 2, 1992 SUBJ: Geographic Information Systems WHAT IS A GIS? MAYOR Edward B. Mc Menomy COUNCILMEMSERS Sheila Klassen James (Red) Steals Harry Willcox Dennis Wippermann ADMINISTRATOR Stephan Jilk A Geographic Information System is a computer mapping system with a geographic database management system integrated with the map. Simply described it allows you to associate data with physical features on a map (ie. property owner, lot size, land use etc. of a parcel; size, depth, year installed, maintenance record, etc. of a sewer pipe segment; location of a fire hydrant). I have attached a booklet entitled "GIS in the 1990's" that does a good job of overviewing GIS and the advantage of this type of system. WHAT STEPS HAS THE CITY MADE TOWARDS GLS? Since 1990, the City Engineering and Planning staff have been working with Dakota County towards the development of a Geographic information System for the City. In 1990, Dakota County, Dakota Electric and the City entered into a cost sharing agreement of aerial photography and stereo digitizing. Through this arrangement the City was able to have very outdated aerial photography updated and the physical land features digitized into a computer digital file. The City's cost was $44,725 or 44 percent of the total cost. The aerial photography provides location and sizes of all existing buildings, houses and small structures. The stereo digitizing enabled the development of data regarding physical land features utilizing elevations, contour lines, water bodies, wooded areas, street locations, etc. The County has also digitized the parcel boundaries and has integrated with this topographic map. The City has been provided hard copy maps of this data in the half section, 200 scale maps and the aerial photography. The County would like to provide the City a digital copy (Computer file) of the data, but presently the City has no software that can utilize the data. The County has developed its database on the ULTIMAP GIS software. If you are at all familiar with GIS software, you may know that ULTIMAP was developed by Hennepin County staff and then the product was sold by the County to ULTIMAP. It is a good system but its major drawbacks are that it must operate on a Unix workstation (vs Personal Computer) and that ULTIMAP has been slow to develop applications. The Company reorganized under Chapter 11 in 1991, but has not been able to get its feet back on the ground. Earlier this summer, the Dakota County Surveyor's office announced that they will be switching to a different software --ARC INFO developed by Environmental Systems Research Institute, Inc. (Sverylkings (Poming (Up (Rosevnounll! Geographic Information Systems October 2, 1992 Page Two This switch has simplified the City's selection of a GIS software. The ULTRVIAP workstation would have cost the City at least $45,000 initially, so Planning and Public Works staff had been exploring lower cost alternatives. In 1990, the City Engineer was considering purchasing a personal computer based software called DIGICAD. In 1991, the company developing that software quit supporting that product. Since that time we have been exploring several personal computer based software and were seriously considering PC ARC INFO when the County decided to purchase an ARC INFO license. WHAT is REcoNmENIDED? We are fortunate to have a head start with the development of a GIS system with the joint database development effort of the County. The staff has attempted to put together a system that will provide immediate paybacks to the City and its citizens. Those paybacks will come in two ways 1) more efficient retrieval of information and 2) enhanced and more accurate information. Ultimately, this should help all of us make more informed decisions. It is important to note, however, that just like purchasing a house, a GIS system will require ongoing maintenance and enhancements to keep it up to date. Staff is recommending that the development of this system will occur in three phases. In the first phase we will acquire the GIS software and needed computer hardware in order to utilize the data base that has been developed by Dakota County. This will enable the City to start to customize and develop our own maps using this base information. We will also be obtain a computer file of the Dakota County Property data base. This will enable us to automate such functions as public hearing mailing notices. In phase two, the City will be enhancing the database by adding all of the City utility information. With a system selected, we will be able to take steps immediately by requiring compatible digital files for all new plats in the City. Existing utility lines and facilities can be added to the system as time and resources permit. Our goal would be to accomplish this over the next two to three years. Most likely this work would contracted out because it is usually more cost effective and accurate to go to a service bureau that specializes in this work. The cost of this task depends greatly on the level of detail and accuracy required. Initial estimates suggest that the task may cost up to $20,000. The third phase, would involve enhancing the software, and networking the system to make it available to more users. The will open up opportunities for developing specialized applications just for the City of Rosemount. Such applications could include engineering and design, integrating facility management systems with GIS, land use and environmental analysis, economic development, and performance zoning applications. Implementation of this third phase will probably begin in 1994 or 1995, depending on the status of the utility database development. Geographic Information Systems October 2, 1992 Page Three WHAT WML NEED TO BE PURCHASED IN 1992? Staff is recommending that a vendor be hired to provide the City with a turnkey GIS system. The software combination that we are recommending includes the purchase of PC ARC CAD, AUTOCAD, and ARC VIEW. The ARC CAD software is a GIS software that uses the AUTOCAD (computer drafting program) as an engine. This combination will provide our engineering, parks and planning staff with computer drafting, database and GIS capabilities. The ARC VIEW product works with the ARC CAD product. it runs in a windows environment and it is very user friendly. This will enable staff that will incidently use GIS accessibility to the system without intensive training. With limited training of about an hour, any one will be able to view GIS information. ARC VIEW does not allow modifications to the data or graphic information, so this will enable more employees to use the GIS without worrying about the security of the data. The software and database requirements of the basic GIS system will require the purchase of a 486 computer with ample storage capacity. To insure hardware and software compatibility, we have decided that it would be advantageous to purchase the hardware and software from the same vendor. We will also be asking that the vendor install the software and obtain and load the data files available from the county. There are three licensed ARC INFO dealers in the Twin Cities area and we will be receiving quotes from all three vendors. The City has some existing equipment that can be utilized with the proposed system: an 11" x 17" digitizer and a D sized 4 pen plotter. The 1993 budget includes training for one staff person and a color ink jet printer. ARC INFO (SSRI) also has a local support office in Eagan. They do not sell the personal computer based software directly, but they are willing to provide on-site demonstrations of these products. I am in the process of arranging a demonstration of the GIS system during the month of October for the Council members and all of the City Commission members. On Tuesday, I will provide the details of those arrangements. If the City Council endorses and authorizes this project to proceed, I would anticipate that the system specifications can be developed by the end of October. If a vendor is awarded the project at the first meeting in November, the City's GIS could be in service by the first of the year. GIS IN THE 90'S WHAT IS GIS? NUJ NEEDS ONE?

TO SUCCESS m The best of both worlds ENVIRONMENTAL SYSTEMS RESEARCH INSTITUTE, INC. The Synergy of CAD and GIS ArcCADTm links the world's leading GIs software to the world's leading CAD software. With ArcCAD's new approach, the limitations associated with integrating GIs and CAD have been removed! This is because ArcCAD is not implemented as a GIs built on top of AutoCAD& , but as an extension of the AutoCAD data model to incorporate ARC/INFOa GIs functionality. ArcCAD extends the AutoCAD data model for creating topological and spatial database relation- ships, and for communicating with entities of an AutoCAD drawing database. Integration With ESRI Product Line ArcCAD is not an AutoCAD'—ARC/INFO data translator, but a complete GIs that creates geographic data directly in native ARC/INFO format. This means that ArcCAD is fully integrated with the rest of the ARCANFO product line. • ArcCAD can use data created by ARC/INFO and PC ARC/INFO$- • Because it is an extended version of AutoCAD, ArcCAD can use AutoCAD drawing files. • Data created in ArcCAD can be used by ARC/INFO and PC ARC/INFO. • ArcCAD can be used to access and process the hundreds of ArcDatal geographic data sets made available through ESRI's cooperative geographic data publishing program. • ArcViewrm software for PCs, Macintoshes, or worldtations can be used to view, display, and analyze ArcCAD data. • ArcCAD can also be used for accessing dBASE"', DXF, ASCII, and IGES f les. The Best of Both Worlds ArcCAD brings true ARCANFO client/server GIs functionality to the desktop. It lets you spend less time trying to balance between CAD and GIs, and spend more time being productive. ArcCAD is the best of both worlds! Easy Data Entry and Editing Creation and editing of GIS data sets have never been more simple than they are with ArcCAD! Coverages are created and edited using AutoCAD's powerful drafting and editing tools. ArcCAD includes GIS tools for the creation, update, and manipulation of topologically structured data. Sophisticated Selection and Query ArcCAD gives you a comprehensive set of powerful GIs selection and query commands—a new concept in AutoCAD. Selection of objects can be based on any combination of spatial, graphic, and attribute criteria specified as a series of logical expressions, making both spatial and relational database queries available within the AutoCAD environment. POLYGON OVERLAYS Union +M Theme I Theme 2 Union: Idenriry All features and attributes of theme I & 2 are preserved in the output theme. Identity: Only these features overlaying the feature extents of theme I are preserved. Feature attributes of both themes are joined in the output theme. Interest: Intersect Only those features in the area common to both arc preserved. Feature attributes from both themes are joined in the output theme. Extended Development Language ESRI has developed special tools for geoprocessing that have in effect extended the capabilities of Autol-ISP11. All ArcCAD functions are also available via AutoCAD libraries. Compatibility With Other Applications As an AutoCAD -based application, ArcCAD can be seamlessly integrated with hundreds of other AutoCAD -based applications to provide such functionality as scanned raster image display and editing, project management, civil engineering, surface modeling, animation, and much more, giving you the most open, flexible, and expandable solution available in the GIS industry today. Powerful Analysis and Modeling Tools Analysis and manipulation tools in ArcCAD let you perform polygon overlay, line- and point -in -polygon overlay, buffer creation, dissolve, and more. These tools can be combined in meaningful sequences to develop new models of spatial reality. Simplified Key Legend Creation The creation of key legends is automatic in ArcCAD, based on attributes stored in the database and a few parameters for which the user is interactively prompted. ArcCAD softnsare expands the usabiliq• of GIS by making it available to the more than 500,000 AutoCAD sites throughout the world. !n addition to provicling an integrated environment for traditional users of GIS and CAD, it also opens GIS technology to a variety of new applications. - Transportation Engineering ArcCAD is the perfect tool for corridor analysis for the transportation engineer. The integration of CAD and GIs provides the ideal platform for drainage design and watershed analysis. Facilities Management Facilities managers use ArcCAD for inside and outside plant management in support of such diverse applications as real estate and property inventory and management. new site selection. and inventory control. Tools for Application Developers In addition to being an end user geoprocessing tool. ArcCAD is also available to the hundreds of developers that build AutoCAD -based applications. AutoCAD application develop- ers can take advantage of the ArcCAD Developer's Kit to provide vertical solutions for numerous diverse disciplines. ArcCAD software's spatial relationships, topological database, and selection, query, and analysis tools give new power for the development of specialized applications in AutoCAD. Civil Enoineerina Civil engineers use ArcCAD for site selection, site analysis. soil analysis and classification, and man other applications. ArcCAD lets the civil engineer use tradi- tional AutoCAD -based coordinate geometry. topography, and road and subdivision design software. while buildint, a GIs database that is topologically correct. How Is ArcCAD Packaged? ArcCAD is packaged as a single product, containing all menus, GIS functions, LISP capabilities, developer's libraries, and user documentation. It runs on DOS-based PCs and requires AutoCAD 386 Release 11. As an AutoCAD -based technology, ArcCAD uses the peripheral devices supported by AutoCAD. How Is ArcCAD Licensed? ArcCAD is licensed by ArcCAD dealers, a network derived from PC ARC/INFO distributors and AutoCAD dealers, and directly by ESRI. How Can I Get More Information About ArcCAD?

Usine the AutoCAD De- velopment System (ADS) in AutoCAD Release 11, SSRI has built ARC/INFO functionality into AutoCAD. ArcCAD software is an extension of the AutoCAD data model that enables users to per- form topological and spa- tial database relation- ships, and to communi- cate with entities of an AutoCAD drawing data- base. Geographic data created in ArcCAD are identical to those used by ARC/INFO, therefore translation of data through intermediate file formats such as DXF or IGES is no longer re- quired. Linking CAD and GIS CAD and GIS are funda- mentally different tech- nologies. The distinct technical differences be- tween CAD and GIS re- sult from the fact that the two systems are designed to do two different things. CAD and GIS function- ality both fulfill specific needs. Today, more than ever before, CAD and GIS are seen as increas- ingly complementary rather than mutually ex - elusive. Diverse disci- plines within organiza- tions are realizing the ben- efits of coordinated implementation of CAD and GIS. and the needs of organizations are increas- ingly tending to overlap. putting more pressure on CAD and GIS vendors to offer fully and truly inte- grated solutions. However, the basic differences between the two systems have made attempts at true integra- tion somewhat difficult. While methods of trans- ferring data between the two systems have been available, this has resulted in only a partial solu- tion—more of a peaceful coexistence than true in- tegration. Some vendors of CAD and GIS have ArcCAD softisare brings familiar ARG/NFO operations for the creation, update, and manipulation of topological data, such as BUILD and CLEAN, into the AutoCAD environment. made attempts to bridge the gap between the two technologies by using a CAD data model for G IS. These attempts have mostly resulted in less than acceptable solutions because of the severe limitations to GIS func- tionality imposed by the CAD data model. By taking advantage of recent developments in CAD technology, SSRI has overcome these diffi- culties to produce the first truly integrated GIS and CAD combination. Not Just Another Pretty Interface More than just an inter- face, ArcCAD software represents a much more important achieve- ment: the marriage of ARC/INFO and AutoCAD functionality. It immediately expands the usability of GIS by making it available to the more than 500,000 AutoCAD sites through- out the world. It doesn't do this by compromising the data model, but by taking advantage of the power of ADS to make the capabilities of the ARC/INFO software and data model available froth within the AutoCAD en- vironment. It also gives ARC/INFO users easy access to the hundreds of AutoCAD add-on products developed by vendors for specialized applications. In addi- tion, ArcCAD makes ARC/INFO functionality available to developers for enhancing AutoCAD applications ArcCAD Concepts The most important con- cept of an ArcCAD data model is that it creates an explicit link between the AutoCAD data model and the ARC/INFO data model in order to pro- vide GIS functionality. ARCANFO GIS data- bases are linked tightly with the geometry of the AutoCAD drawing data- base. A theme is an organ- izing principal in ArcCAD software, used to group a set of entities that have some common properties. It is the link between the AutoCAD layer and the ARC/INFO feature type. There are six basic theme types in ArcCAD: points, lines, polygons, annotation, tics, and records. Records are special features that do not have a graphic representation, but link graphic features to attribute values stored in dBASE files. .PATS and .AATs—concepts fa- miliar to ARC/INFO us- ers—are completely transparent to users of ArcCAD. ArcCAD Features Creating and editing to- pologically correct geo- graphic data sets have never been more simple than they are with ArcCAD software. Cov- erages can be created and/ or edited in AutoCAD using all of AutoCAD's powerful graphic tools. ArcCAD includes famil- iar ARC/INFO opera- tions for the creation, up- date, and manipulation of topological data, such as CLEAN and BUILD. ArcCAD gives users all of the powerful GIS selection and query com- mands found in ARC/ INFO—a feature not available in AutoCAD. Selection of objects can be based on any combi- nation of spatial, graphic, and attribute criteria specified as a series of logical expressions. ArcCAD software provides a user-friendly and easy -to -learn envi- ronment for the study of real-world geographic processes by developing and applying geographic models. Analysis and manipulation tools in ArcCAD let users per- form polygon overlay, line- and point -in -poly- gon overlay, buffer crea- tion, dissolve functional- ity, and more. These tools can be combined in meaningful sequences to develop new models of spatial reality. Models developed in ArcCAD may reveal new orpreviously unidentified relationships within and between data sets, thus increasing the under- standing of the real world. The creation of key legends, a tedious man- ual process in AutoCAD, is automatic in ArcCAD. Just as in ARCANFO, the user is interactively prompted for a few para- meters, and the key leg- end is automatically cre- ated. All ArcCAD func- tions are also available via ADS and AutoLISP functions. Because of the fundamental differences between GIS and CAD, ESRI has developed spe- cial tools for aeo- processing that have in effect extended the capa- bilities of AutoLISP. Tools for Application Developers In addition to being an end-user geoprocessing too] ArcCAD software is also available to the hundreds of developers that build AutoCAD - based applications. AutoCAD application de- velopers can take advan- tage of the programmers' libraries to provide verti- cal solutions for civil en- gineering, municipal planning, electrical facili- ties management, real es- tate management, and other diverse disciplines. ArcCAD's selection, query, and analysis tools enable the development of a realm of specialized applications neverbefore possible in AutoCAD software. Integration with Other ESRI Products ArcCAD software is fully integrated with ESRI's entire product line, and ArcCAD main- tains data in ARCANFO format. Using ArcCAD, you can display, edit, and analyze coverages cre- ated in ARCANFO and PC ARCANFO. Cover- ages created in ArcCAD can be used in ARCANFO and PC ARCANFO. Similarly, you can use ArcView from your PC to look across a net- work and view, display, and analyze ARCANFO coverages created in ArcCAD. Because of the integration capabilities of ArcCAD, ArcView be- comes a front-end tool for the visualization of both ARC/INFO and AutoCAD data. ArcCAD Packaging The ArcCAD product contains all menus. GIS functions. LISP capabili- ties, and so forth, needed to give you comprehen- sive GIS functionality from within AutoCAD. It runs on DOS-based PCs and requires AutoCAD 386 Release 11. As an AutoCAD -based tech- nology, ArcCAD uses the plotters, digitizers, and other peripheral devices supported by AutoCAD. ArcCAD Release Schedule ArcCAD software will be demonstrated at the GIS/ LIS conference in At- lanta, October 29-31, 1991. SSRI is planning to release ArcCAD on the 386 platform in early 1992. A Sun SPARC station port of ArcCAD is also planned. ArcCAD Will Make Users More Productive ArcCAD software lets users spend less time try- ing to balance between CAD and GIS. and spend more time being produc- tive. With the introduc- tion of ArcCAD, SSRI brings users the best of both worlds. 1991 by Environmental Systems Research Institute, Inc. All rights reserved.
