    When will the next orthophotos be available?

    The next Pictometry aerial photo project is planned for spring of 2018.

    The Pictometry project flown in April and May of 2016 is the latest available imagery.  Oblique and orthophoto views are available using the PimaMaps and MapGuide "Oblique Aerial Photos" tools as well as Pictometry links toward the bottom of parcel information pages. 

    The 2016 Pictometry orthophoto layer is included in the PimaMaps "Latest Orthophoto Imagery" layer and is available on MapGuide maps.

    How do I get orthophoto and aerial imagery data files?

    See Getting Orthophotos and Aerial Imagery.

    How come I can't check the layers and groups on and off in map legend?

    See dual monitor help for this problem.

    How come the yellow map tips disappear when I hold the mouse?

    When you're working in another window and then hover over map features in MapGuide, the displayed map tips disappear so quickly you can't even read them. This happens when the MapGuide window is no longer the active window. That is, the MapGuide window has lost "focus". The solution is to click anywhere in the web browser MapGuide window to make it the active window. Then the map tips will work normally and stay in place as you hold the mouse over a map feature.

    Where do I find all the utilities?

    The only utility available on our MapGuide maps is the sewer network maintained by Pima County.

    • Sewers are mapped in the "Sanitary Sewer - Pima County Maintained" layer group on the Main MapGuide Map. The sewer system is operated by Pima County Regional Wastewater Reclamation Department for most of Pima County. They provide the map sewer data for our maps.
    • Tucson Water does not provide us with map data for our MapGuide maps. Selected area maps are available from Tucson Water Customer Services at 310 W. Alameda St. in Tucson.
    • All other utilities are operated by companies that do not share their map data with us. These include electric, telephone, gas, and cable.

    How often are the data layers updated?

    Data update frequency varies considerably as each data layer is maintained separately.

    • Some layers such as "Parcels - Pima" are maintained daily or concurrently with the data changes, such as "Annexations". Even so, parcel information like the parcel owner is based on assessor records which may lag recorded parcel changes by a few months.
    • Other important layers like the "Streets," "Subdivisions" and "Zoning" are maintained on a regular basis.
    • Other layers may be updated as infrequently as yearly.
    • Some layers originally created for special projects have no update plan.
    • Orthophoto imagery is updated after each new orthophoto project is completed. See Orthophoto Imagery for more.
    • Lastly, there are layers such as the Section Grid that don't require maintenance.
    Our GIS Library Data Layer Metadata includes the Date of Last Update, as well as the Source Date and a Maintenance Description for each layer. This update information is maintained manually. Certain updates may not be reflected in the metadata. Conversely, the update date may be the date we updated the library and may not necessarily be true date of the underlying layer. When the update date is important to you, you should seek confirmation of the data from official sources.

    When is the next MapGuide class?

    MapGuide classes have been suspended. No classes planned at this time.

    How do I print the map? Why can't I print?

    See Printing the Displayed Map.

    How can I see the latitude and longitude?

    There are several ways to display and capture the latitude and longitude of one or more points on the map:

    1. The simplest way is to see the latitude and longitude of the cursor position in the status bar just under the map legend on the left. Just move the mouse on the map and see the latitude and longitude in the status bar. The latitude and longitude are displayed in decimal degree format. Your MapGuide Viewer Preferences need to be set to display the mouse position to make this work. To set or verify your Preferences settings, right-click in the map, choose Preferences..., then ensure that "Display mouse position" is checked, and that "Latitude, Longitude" units are selected. The displayed values change when you move the mouse, making it impossible to copy and pasted the values using this method.
    2. Internet Explorer on Windows users can use the "Get Lat/Lon" tool in the "Map Tools & Map Info." drop-down list box at the top of the map to show a report of all selected point map features. Select one or more point map features or use the Draw Point tool to add points to select. See

    How can I zoom to a latitude/longitude on the map?

    There is a "Zoom to Lat/Lon" tool in the "Map Tools & Map Info." drop-down list box at the top of the map. This allows Internet Explorer on Windows users to zoom to latitude/longitude values from inside MapGuide. You can also use the tool to convert between decimal degrees and degrees/minutes/seconds formats you enter. If you aren't using Internet Explorer on Windows, there is a link at the bottom of our main MapGuide Maps page that lets you Enter latitude and longitude and zoom to a MapGuide map location by opening a new map window.

    How can I find a parcel's area?

    See Finding Parcel Areas.

    How do I print mailing labels?

    See MapGuide Tutorials for Creating Reports and Creating Mailing Labels.

    How do I get the source map data files to use in other programs?

    See GIS Data Products - Acquiring Our GIS Data.

    Where can I find MapGuide for other Arizona counties?

    Not all counties or cities have online interactive mapping. Pima County was one of the first to provide this service to the public on the Internet, starting in the fall of 1997. Other jurisdictions may use MapGuide software or they may use different mapping technology. Unfortunately, there is no standardization of the technology or mapping presentation. See Arizona Counties for links to other county maps we know of. You may also find our own Arizona MapGuide Map helpful.
