Hello, I am looking for a collection of animal location data collected via telemetry. Any animal would do! The Canadian government used to house a downloadable record of Porcupine Caribou telemetry data that reached back into the early 2000s. Those data have since been removed and their access requires a four-page application and review by a scientific panel. I don't really want to jump through those hoops. My primary interest is to use such data in a training manual, specifically for the use of Geospatial Modeling Environment (Spatial Ecology) tools to analyze animal movements. Any help or guidance anyone could provide on where to access such data would be greatly appreciated. Thanks in advance. ... View more

Hello, I have created a river network for a fairly large area (1,014,142.15 km2) using 90-meter SRTM tiles. This river network was not created with ArcHydro tools, but with standard Spatial Analyst Hydrology tools. The stream order of the derived river network ranges from 1 to 7 (Strahler). I would like to delineate watersheds for each stream for each stream order. That is, I want watersheds for each stream classified as 1, each stream classified as 2, and so on all the way up to 7. Manually creating the pour points for each stream is a rather tedious and time-consuming process. Is there a way to identify unique pour points for each stream? I would like to avoid identifying one pour point per junction. For example, at the junction of two class 5 rivers I would like to have two points - one identifying the pour point for the first river and the other identifying the pour point of the second, so that two distinct watersheds are created.  Is there a tool or process by which I can create such unique pour points as opposed to doing it manually? Thanks very much. ... View more

Hello, My DEM (SRTM 90m) has sinks, as made clear by the output of the Flow Direction and Sink tools. I can fill these sinks with the Fill tool with no problem. But I wanted to take a more precise approach by following the "Finding Sink Depth" process as outlined on the page, "Creating a Depressionless DEM". I followed each of the 5 steps outlined and determined that the maximum sink depth was 33 meters, as the output of the Minus tool ranged from 1 to 33. I ran the Fill tool on the original DEM and specified a z-limit of 33 and then ran Flow Direction on this output. The Flow Direction output was the same as the Flow Direction output from the original, un-filled DEM. In other words, the "Finding Sink Depth" approach didn't work, unless I missed a step or made a mistake somewhere in there. Anyone encounter a similar problem? Any thoughts or guidance would be most welcome. Thanks. ... View more
