  • We took existing CAD Data, geospatially referenced to our District Coordinate System and converted to our GIS system such as: Streets, Buildings, District Boundary, Water Pressure Zones, Topography, an aerial photo and our Map Panel Grid. Zach used this CAD data to make our 2010 wall maps and map books . El Paso county had a lot of data to choose from such as Parcel information, section lines, other water districts, street names, and municipalities. We converted the data to our coordinate system and will receive updates from El Paso county every six months , to keep our system up to date.
  • We hired a GIS intern , Christina, for the summer term to collect and verify GPS points using our Trimble Geo XH . She collected our water valves, manholes, hydrants, blow offs, wells, water treatment plants, pump stations, our waste water treatment plant, pressure reducing valve’s, pressure sustaining valve’s, storage tanks, metering stations and lift stations. Christina brought GPS points in and I transferred the data from the Trimble unit into GPS Pathfinder Office for differential correction. Then exported it into Arc Map to analyze the data for point accuracy. Some points had been previously collected in 2006 & 2007, so I compared accuracy and kept the points with the best PDOP . PDOP is determined by satellite signals, so different days produced different results. Zach had put a lot of thought into the symbols he used for last years CAD map , so we matched as many as possible and picked some new. Published map for Arc Reader , which is a view only version of my working map in Arc Map that can be viewed on any office or field staff’s personal computer. I add new data , correct old data to keep our map up to date. Zach does a lot of the cartography of the map, changing zoom scales and appearance, then we republish our latest versions for Arc Reader . We’d like to give you a demonstration of Arc Reader and it’s functions.
  • Yet this fall Zach and I will begin connecting pipe mains to our water and sewer points from existing data in H2O Net and Sewer Map . We’re comparing different software for the infrastructure and read only versions of our maps to find the most user friendly versions. We plan to purchase software to integrate our current systems with our GIS system. This will eliminated steps in correcting data. Corrections can be made in Cartegraph or Caselle and the GIS system would instantly update .
  • As soon as next year, we hope to have digital maps for our operators . A Hydraulic Modeling System for our GIS Database. Be able to share our information with El Paso County and the fire department . In the summer we hope to hire another intern for more GPS point collection. A major goal is to have all departments sharing up to date information through the GIS System.

    2. 2. Goals of District Mapping <ul><li>Map Objects are Geographically Correct and Contain Intelligent Attributes </li></ul><ul><li>Integrate Infrastructure, Billing, Asset Management, Engineering, and Property Information into a Single Digital Database </li></ul><ul><li>Entire District Staff can access this Mapping System from their own Desktop PC or in the Field using Mobile Applications </li></ul><ul><li>Published District Maps and Exhibits are Accurate and Precise </li></ul><ul><li>GIS Database Used for Improved Planning, Engineering, and Operations of the District </li></ul>
    3. 3. What is GIS/GPS? <ul><li>GIS (Geographical Information System) </li></ul><ul><ul><li>Captures, integrates, stores, edits, analyzes, shares, and displays information linked to a geographical location </li></ul></ul><ul><li>GPS (Global Positioning System) </li></ul><ul><ul><li>Global navigation satellite system that provides reliable location and time information </li></ul></ul>
