Introduction: LROC Lunar Image Interface Tutorial
Did you know that you have FREE access to powerful Lunar image viewing interfaces? Actually there are several but this tutorial focuses on the one that I feel has the most to offer.
Arizona State University processes and host's the data returned by NASA's Lunar Reconnaissance Orbiter Camera imaging satellite that has been orbiting and photographing the Moon since 2009. This simple tutorial can guide you through the features and functions of the interface and may be helpful to those who have never used the product.
1. Right click here LROC WMS Image Map and select open in a new tab, or window.
2. If you have target coordinates enter them in the appropriate boxes then click Recenter. If you don't have target coordinates and just want to explore you can use the Navigation controls to rotate the globe until you see something that interests you. Alternatively you can set the mouse-action to Recenter, or Recenter & Zoom and then simply click a location of interest on the globe.
3. Use the zoom control to zoom in and out. The initial maximum zoom resolution is 49.8 km on the scale.
The default image map is the LROC imaging satellite data, however the interface also allows you to view image data from the Lunar Orbiter and Clementine missions. Once you switch to the Lunar Orbiter map the maximum zoom resolution increases to .210 km on the scale.
The advanced options are accessed by clicking the Toggle Layers button which opens a sub-menu.
To increase the maximum zoom:
1. Click the Toggle Layers button.
2. Select the Lunar Orbiter Mosaic radio button.
3. Click the Update Layers button at the bottom of the menu.
This will switch the view to the Lunar Orbiter Mosaic however you can switch to any other mosaic now and the maximum zoom resolution will remain at .210 km on the scale unless the page is refreshed.
The remaining Advanced Options turn on or off various information overlays.
NAC= Narrow Angle Camera
WAC= Wide Angle Camera
If you find image 5 of this tutorial of interest I suggest you follow these steps to target that location:
1. Enter these coordinates -28 Latitude -96 Longitude and click recenter.
2. Zoom to 15.7 km resolution. (about halfway up the scale)
3. Switch to the Lunar Orbiter Mosaic for the best contrast and detail.
