Get better search results with queries and filters
Last month a new search tool became available to users of the Online Survey Research GIS. The new tool allows users to build custom queries and set spatial filters. Watch the video and read the post to maximize the GIS and get better search results.

Dense polygon clusters:
Set a spatial filter when the screen is crowded with polygons. This will display small symbols to click rather than the polygons which can be clumsy when they're in a dense cluster.
|Multiple polygons make selecting a single map difficult|
|Smaller symbols help with selecting a single map in a crowded screen|
Areas that have been surveyed more than once will sometimes cause polygons to hide other polygons. Setting filters will reveal all maps in the area with different symbols that still have all of the attributes of the polygons.
|On two areas of this screen a corner record polygon is being hidden by a larger corner record polygon.|
|Setting a filter will reveal all maps and display a different symbol to click and retrieve the map.|
Map polygons are only displayed when the GIS reaches a zoom level of 1" = 600' which is acceptable for most conditions. When searching large areas (higher than 1" = 600') a filter will display maps by symbol rather than polygon.
|No results for Records of Survey at 1 inch = 0.5 mile|
|All Records of Survey shown; click each symbol to download the map.|
