went to the wiki where an example workflow is presented. The example uses<br>
satellite raster data; my data are 25 days of daily precipitation (total and<br>
hourly rate) over an approximate 40 ha area. A bare earth LiDAR DEM for this<br>
area exists.<br>
<br>
Do I make copies of the DEM for each day then replace the elevation with<br>
either the daily total or the hourly rate for each day?<br>
<br>
For the t.create parameters I know type = strds but have no idea what<br>
temporaltype or semantictype to specify. (N.B. The manual page example has<br>
no value for semantictype and that's supposed to be required input.)<br>
<br>
Where do I find the information I need to create this temporal database?<br>
