Wadi Ziqlab DEM
This is a jpeg image of a 10 meter resolution DEM of the Wadi Ziqlab and surrounding area in Northern Jordan. The Jordan valley is the green area on the left half of the image, and Wadi Ziqlab is the long fingering drainage just below center. Wadi Tayba is the long narrow drainage just above it, and Wadi Abu Zayid is the small drainage just below it.
Hillshade DEM of Wadi Ziqlab
This is a jpeg image of a hillshade DEM developed from the above DEM and then draped with the colors of the above DEM. Any other raster layer can be draped over a hillshade. Sattellite photos, soil raster maps, and land cover raster maps are brought to life by draping them over hillshades.
3D Visualization of Wadi Ziqlab
- 3D visualization gives us a better feel for the terrain of the Wadi Ziqlab area. Starting from the left we can see Wadi Tayiba, Wadi Ziqlab, and Wadi Abu Ziad. The vertical exageration has been set to 1.25 to help emphasize subtle terrain changes. The resolution of this visualization is 10 meters. Like a hillshade, other raster layers can be overlayed to bring them to life.
Satalite imagery
10 meter NIMA SPOT image overlayed on the topography layer.
Satellite blow up of the town of Dayr Ab' Sayid
Dayr Ab' Sayid is the town nearest to Wadi Ziqlab, and is where the field crew lives during excavations.
Geology of Wadi Ziqlab Area
This is an overlay of the major geologic strata (provided by the USGS) of the Wadi Ziqlab area.
Wadi Ziqlab Slope Map
This is a 3-D overlay of the slope raster for the Wadi Ziqlab area.
Length-Slope map
The length-slope map is a rater layer which depicts the ideal erodability if soil type, land cover, and hydrography were all equal. Essentially, it is a factor of how many raster cells lay upslope from a certain cell, and how steep the gradient is.
Download Geospatial Datasets
Wadi Ziqlab GIS datasets are available here.1:200,000 queriable Geology maps (GRASS format) are available here.
IMPORTANT: These datasets are a result of many long and arduous hours of work that I have done as a part of the on-going MEDLAND research project at ASU SHESC. We are happy to share data, but since the project is not yet complete, this data is not yet public domain. Therefore please ask me for permission before downloading or using these datasets for any reason
