GIS data for 2013 U.S. Geological Survey Scientific Investigations Map 3263,"Water-Level Altitudes 2013 and Water-Level Changes in the Chicot, Evangeline, and Jasper Aquifers and Compaction 1973–2013 in the Chicot and Evangeline Aquifers, Houston–Galveston Region, Texas," by Mark C. Kasmarek, Michaela R. Johnson, and Jason K. Ramage


The GIS data are contained in two separate compressed files:

Geodatabase version:
GIS_Data_for_SIM3263_2013WaterLevelChange_Series_GDB.zip

Shapefile version:
GIS_Data_for_SIM3263_2013WaterLevelChange_Series_SHP.zip

Each of these versions contains a metadata directory containing Federal Geographic Data Committee compliant metadata in *.xml and *.txt versions.
\metadata\GIS_Data_for_SIM3263_2013WaterLevelChange_Series.txt
\metadata\GIS_Data_for_SIM3263_2013WaterLevelChange_Series.xml


The data are separated into three feature datasets (three directories for shapefiles) by aquifer that contain the individual feature classes (shapefiles).
   
   Chicot aquifer - (feature dataset name/shapefile directory name)
   Feature classes/shapefiles:
   ch13pt - water-level altitudes, 2013
   ch13arc - approximate water-level altitudes, 2013
   ch1213pt - water-level changes, 2012-13
   ch0813pt - point values of water-level changes, 2008-13
   ch0813arc - water-level changes, 2008-13
   ch9013pt - point values of water-level changes, 1990-2013
   ch9013arc - water-level changes, 1990-2013
   ch7713pt - point values of water-level changes, 1977-2013
   ch7713arc - water-level changes, 1977-2013

   Evangeline aquifer - (feature dataset name/shapefile directory name)
   Feature classes/shapefiles:
