This code is meant to be used to search and explored Planet Labs' catalog of PlanetScope 4 band datasets. The data is uncalibrated and in it's raw state when downloaded with only an ENVI header file being added that contains the band information associated with the data.

Note that this extension needs a PLanet Labs' API key to access the data. The key that you have may not work in all regions of the world or for the data products that are downloaded by the extension. Make sure to check with Planet Labs' for any issues that you may be having due to API keys.

ENVI 5.3 and IDL 8.5 or newer

API key to access Planet Labs' data

There are two different installation options depending on the software that you have.

If you have ENVI + IDL, then you can either:

1. Place the IDL code directly in ENVI's extension folder. This work's ONLY when you start ENVI + IDL at the same time so that ENVI can compile code on the fly.

2. Build an IDL SAVE file and place that in ENVI's extension folder. This works with or without IDL.

To build the save file you can see the section Building the SAVE file (requires IDL) below. The next section Only ENVI lists the locations where the SAVE file should be installed so that ENVI is aware of the extension.

Place the IDL SAVE file, planetcatalog.sav, in ENVI's extension folder which depends on the version of ENVI and the rights that you have as a user.

For ENVI 5.3 and admin rights the directory for Windows is C:\Program Files\Exelis\ENVI54\extensions

For ENVI 5.4 and admin rights the directory for Windows is C:\Program Files\Harris\ENVI54\extensions

If you do not have admin rights then you can find the local user directory in ENVI under:

File -> Preferences -> Directories -> Extensions Directory

Once you place the file in ENVI's extensions you must restart ENVI before you will see the new tool in ENVI's toolbox.

To build an IDL SAVE file for a custom version of ENVI / IDL you need to issue the following commands in IDL:

1. Press the "Reset" button in the IDL Workbench

2. Open planetcatalog.pro in the IDL workbench and make sure it has keyboard focus in the editor.

3. Press the "Compile" button in the IDL workbench

4. Issue the following commands from IDL to save the pre-compiled code to disk:

   save, /ROUTINES, FILENAME = 'planetcatalog.sav'

   Optionally you can provide a fully-qualified filepath for the FILENAME keyword such as :

   save, /ROUTINES, FILENAME = 'C:\Users\yourUsername\Desktop\planetcatalog.sav'
