Tarsier journal: Carmel Watershed
From CCoWS Wiki
This page is intended to record a journal of data processing and analysis steps take by various folks in the Carmel Watershed using Tarsier. Its half scratch-pad, and half-tutorial.
Goals
- Get a watershed model up and running for the Carmel Watershed.
Obtaining a DEM
- Follow steps in Tarsier tutorial: Raster data and Tarsier tutorial: Raster resampler
- Select a 1/3" NED DEM i.e. about 10 meters.
- Select ArcGRID
- Download data in GridFloat format
- Change extension of main file from ".flt" to ".raw"
- Open ".raw" file in Tarier, use the ".hdr" file to fill in properties
- Save as Tarsier raster (.tra)
- Convert raster from lat/long to UTM using raster resampler
Creating a Visualization of the Watershed
- Fallow steps in Tarsier tutorial: Renderer, Adding Agents, Tarsier tutorial: Simple fly-through and Tarsier: Importing shapefiles
- Open a renderer veiw
- Open Carmel 10m raster as well was terrain file made following renderer tutorial
- Explore the terrain using the flight keys
- Add cams to make a simple flight of what was thought to be whole length of the Carmel River
- Add label agents and realize the flight began in Cachagua Creek instead of the Carmel River... Oops.
- Redo the flight to fallow the Carmel River
- Adjust the ins and outs of the cams to make the flight smother (this trick is not found on the flight wiki page yet... ill do that soon)
- Use a more aesthetic color scheme (maybe make a tutorial on making and saving color schemes?)
- Adjust the timing of the flight to be under a minute
- Record the flight, view the flight and make necessary changes
- Add vector data representing water in the channel
- I used Arc to make the vector data because I did not know how to do it in Tarsier
