GIS Downloads
We offer a wide range of downloadable GIS Layers:
gcmrc_mile
- This coverage contains points representing whole miles in the GCMRC river mile system. The points fall along the centerline of the Colorado River from Glen Canyon Dam to the headwaters of Lake Mead.
- Meta-Data: gcmrc_mile.xml -- .xml format (23 KB)
- Data: gcmrc_mile.e00.gz -- .gz format (37 KB)
gcmrc_tenthmi
- This coverage contains points representing tenth of miles in the GCMRC river mile system. The points fall along the centerline of the Colorado River from Glen Canyon Dam to the headwaters of Lake Mead. The points were generated from exported nodes from the "centerline" tenth_mile route.
- Meta-Data: gcmrc_tenthmi.xml -- .xml format (22 KB)
- Data: gcmrc_tenthmi.e00.gz -- .gz format (191 KB)
gcmrc_tenthkm
- This coverage contains points representing hectometers (100 meter intervals) from the Glen Canyon Dam. The points fall along the centerline of the Colorado River from Glen Canyon Dam to the headwaters of Lake Mead. The points were generated from exported events from the "cl_hectometer" hectom route.
- Meta-Data: gcmrc_tenthkm.xml -- .xml format (16 KB)
- Data: gcmrc_tenthkm.e00.gz -- .gz format (191 KB)
ltm_reaches
- Integrated Long Term Monitoring Reaches were developed by the GCMRC and its cooperators to focus interdisciplinary research in limited reaches for the synergistic advantages of coordinated research and for cost savings. The reaches were developed and revised by the GCMRC GIS after multiple reviews by the staff and cooperators. These reach boundaries are approximate and should be used for planning purposes only.
- Meta-Data: ltm_reaches.xml -- .xml format (8 KB)
- Data: ltm_reaches.e00.gz -- .gz format (207 KB)
qqq_index
- This is a GIS Index Layer for the Digital Imagery and Digital Elevation Data acquired along the Colorado River in Grand Canyon since May 2002. This region coverage should be used to locate specific quarter-quarterquad (qqq) tiles of RGB, CIR, DSM, and Band Separates.
- Meta-Data: qqq_index.xml -- .xml format (16 KB)
- Data: qqq_index.e00.gz -- .gz format (117 KB)
