Updates to the Geologic Map Service (3/19/13)As always, we welcome your feedback at:
The map layers and service should be working normally now. Apologies for any issues experienced in the past few weeks.
Updates to the Geologic Map Service (10/18/13)
- Major Update! Map service now uses the ESRI basemap layers and has all the ESRI basemaps available for use. This has several implications:
- A new layer selection has been added called "Change World Base Layer (ESRI)" to the basemap layer list. Select the basemap you would like to use from the list of thumbnails. The default is the Topographic base. These are worldwide base layers projected in WGS 84.
- The map service projection is now WGS 84 (WKID = 102100).
- The map service should be faster and more stable.
- The KY Topography and KY Imagery layers can still be turned on. These base layers provide detail that the ESRI basemaps do not provide. These are available in the layer list and overlay on top of the ESRI base layers.
- Due to the caching scheme for the ESRI basemaps, the scale levels for the map are different than before. If you need a "standard" map scale of, say, 1:24,000 or 1:100,000 you can use the archived and deprecated (no longer maintained) version of this map service here: http://kgs.uky.edu/kgsmap/KGSGeoServer_arch/.
- New layer added: LiDAR-derived sinkholes. Find this in the layer list under "Water". This layer also turns on when the "Karst Potential Map" layout is toggled. The features in this layer are available for the Floyd's Fork basin near Louisville.
- Data downloads are now being added for some layers. Currently downloads are available for the geologic map data, oil and gas well data, and the LiDAR-derived sinkholes. For those layers that have data downloads (in shapefile or ESRI geodatabase format) you will see a download icon next to the layer name. Click to either download a zip file of the layer or be directed to a page with instructions for download (mouse-over the icon for instructions).
- Search for a place widget (geocoding) has been added to the map interface. This was previously in the tools menu - but is very popular and has been elevated to the map for quick use.
- A scale bar has been added. Displays both metric and english units. Located at the bottom left of the map.
- The fractional scale has been moved to the bottom of the map interface.
- "Well Number" has been added as a label option to both Oil and Gas well ("Oil & Gas Wells" / "Terminated Oil & Gas Permits") layers.
- Terminated oil and gas permits have been added as a separate layer to the service (under the Oil and Gas layers). This was done to help users distinguish between actual wells that have been drilled and permitted locations that may not have been drilled.
- Added a quick search and zoom to an address or placename of interest. Simply enter information into the search box under the "Tools" tab (under the navigation tools).
- Horizontal/deviated oil and gas wells are now designated with an "(H)" next to their label. And deviated wells traces now only display approved permits. Please note that these are only deviated wells that were approved for drilling by KGS, and not all lines are associated with a drilled well record number.
Significant updates have been made to this map service, which include the following:
- A "What's New?" link in the header. This links to this dialogue.
- New (and hopefully improved) printing capability: ESRI has provided some new tools for printing from web map services,
and these have been implemented here. Two printing tools are found under the "Tools" tab. One is for printing to a web page
(and then to your printer using your web browser and system printing capability) and the other is for printing directly to a downloadable
PDF . For each tool,
select a desired page size by clicking on the black triangle. Then, click the "Print" text to print to either a new web window or a PDF. The map will
print to a formatted page with a scale and title and will maintain the current map scale (the map area will vary by the selected page size).
If you want to just print the map image as displayed on the screen, select either "Map Image Only" or "High Resolution Map Image" for this capability.
We are working on capability for downloading a georeferenced map image. Though you can always bring the services displayed on this map application into
a desktop GIS (ArcGIS, Google Earth) using the instructions provided here:
- You can now control the transparency of the raster base layers (topographic map and aerial imagery layers in "Base Layers").
- Added LiDAR 5 ft Hillshade map layer from the KY Division of Geographic Information.
This layer is toggled on/off under the "Special Raster" section at the bottom of the "Layers" list. LiDAR data is available for about a 1/3 of Kentucky.
- Landslide information from the KGS Hazards Section has been added. These data can be turned on by either toggling the data on/off under the "Data Layers" (five types of
data are displayed in this layer), or by simply selecting the "Landslide Information Map" from the "Quick Map Layouts". More information about these data can be
found at http://kgs.uky.edu/kgsmap/helpfiles/landslide_help.shtm.
- Bug fixes, improved map service speed, and improved symbology visibility.
