Geographic information system (GIS) data for 2015 Scientific Investigations Map 3337,"Water-Level Altitudes 2015 and Water-Level Changes in the Chicot, Evangeline, and Jasper Aquifers and Compaction 1973–2014 in the Chicot and Evangeline Aquifers, Houston–Galveston Region, Texas" by Mark C. Kasmarek, Jason K. Ramage, Natalie A. Houston, Michaela R. Johnson, and Tiffany S. Schmidt


The GIS data are contained in two separate compressed files:

Geodatabase version:
GIS_Data_for_SIM3337_2015WaterLevelChange_Series_GDB.zip

Shapefile version:
GIS_Data_for_SIM3337_2015WaterLevelChange_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_SIM3337_2015WaterLevelChange_Series.txt
\metadata\GIS_Data_for_SIM3337_2015WaterLevelChange_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:
   ch15pt - water-level altitudes, 2015
   ch15arc - approximate water-level altitudes, 2015
   ch1415pt - water-level changes, 2014-15
   ch1015pt - point values of water-level changes, 2010-15
   ch1015arc - water-level changes, 2010-15
   ch9015pt - point values of water-level changes, 1990-2015
   ch9015arc - water-level changes, 1990-2015
