General Use

The Small Bodies Image Browswer is designed to let you see/access data in two major ways - Search for images near a point and show a sequence of images. (Note: it is not designed to be an analytical tool, but to find useful data with which you use other tools.) The program has been designed to be quick when looking for data; however, the base database must be downloaded to your machine first. It takes about 2-3 minutes to load.



Limiting the Search

The Dawn mission generated over 30,000 images, and as such, it is very useful to limit how much is displayed at a time. There are several controls that help you limit how much is shown at once. These limits apply for when you do "Search" and "Show Sequence", but not when you do "Search Name"

Quick Reivew of the Surface.

One way to do a quick review of the surface is to select a sequence (such as HAMO 5) and click "Show Sequence." Click the first record in the Image List, which will show you the footprint and preview. Then use your keyboard's down arrow to scroll through the list and see each image taken of the sequence.

Known bugs

Map Projection and Arc-GIS

Data can be imported into ArcMAP 10.1 by downloading the ISIS Map cube.

Most images (PNG and thumbnail) were generated with an equirectangular projection. Images that are near the poles have been projected with a polar projection. Specifically, when the max latitude is greater than 45 degrees.

Maps

We use several different overview maps for the Image Browser. References for each:

Data processing

We used the USGS software tool Integrated Software for Imagers and Spectrometers (ISIS) as the main tool to process the data. We used Gaskell's shape model and the ISIS software routines to convert images into map-based projections.

Coordinates

This software uses the PDS-Vesta-2012, as approved by the IAU. This system is also known as the "Claudia Double Prime." The prime meridian goes through the Olbers region, following the coordinate system established by Thomas et al. 1997. The Prime Meridian is 150.7 degrees east of the crater Claudia.
