Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) Stamp Layer
From JMARS Wiki
The CRISM Stamp Layer will display stamps for all of the observations taken by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard the Mars Reconnaissance Orbiter. While the query interface is similar to the THEMIS Stamp Layer, there are some differences which allow users to search for observations by the many parameters associated with CRISM observations.
[edit] Open the CRISM Stamp Layer
- Open the Stamp Layer: Chose "Add New Layer" -> "Stamps" -> "CRISM Stamps".
- Search Parameter Categories: The search parameters are divided into categories since there are so many of them. Clicking on the down arrow on the right side of the category name will reveal all the search parameters in that category. The categories are:
- Basic Parameters
- Observation Parameters
- Science Parameters
- NOTE: A search can be done with parameters from multiple categories.
- Search Parameter Categories: The search parameters are divided into categories since there are so many of them. Clicking on the down arrow on the right side of the category name will reveal all the search parameters in that category. The categories are:
- Enter Search Parameters: It is not necessary to enter values for each parameter, but the more specific your search the faster it will be. The allowable values for each field are given in the quick reference table below followed by more detailed descriptions of each search parameter.
- Perform Image Search: Clicking OK will make the Stamp Layer perform the search and display the results. Depending on how specific the search parameters are, it may take the Stamp Layer a few minutes to find and create stamps for all of the images. Once the stamps are displayed in the Viewing Window, users can right-click on an outline to view the image in a web browser. (A rendering option for CRISM stamps is in the works, stay tuned!)
