Frequently Asked Questions (FAQs)

How do I search for a particular tract (parcel) of land?
To locate a tract or parcel on the Pine Ridge Reservation, enter the “Tract ID” number into the search form at the top-left corner of the PRLIS. It will automatically pull-up a list of related numbers. Click on the appropriate one and the system should zoom into the boundaries of the Tract of land and highlight in light blue. Note: Lands with a majority ownership held by the Tribe will have a “T” before the number. If you are an enrolled tribal member and you are looking for your own lands, you can find your Tract ID on your Individual Trust Interest Report. To order a copy of your Individual Trust Interest Report call the Office of Special Trustee at 1-800-961-6109.

How do I find out more information about each layer?
You can access more information about each layer or layer subpart by selecting the “Information” button found on the map control tool bar located under the tabs and then clicking on the particular layer or subpart in your map. A dialogue will pop-up on the map with tables of relevant data.

How do I turn on and turn off different layers?
The PRLIS has a number of different layers and backgrounds that you can choose to turn on and off. By default, the PRLIS shows the boundaries of Pine Ridge on top of a basic “streets” background. A layer that has the different land tracts for Pine Ridge is also turned on by default but is not visible unless you zoom to a map scale of at least 1 =54,000. There are several other optional layers including a map of the Range Units for Pine Ridge, the Boundaries as described in the 1851 and 1868 Treaties, a recent Landsat TM image, high resolution aerial photos from USGS,  Google, and Bing, and a Google Physical “topographic” features. To turn these layers on and off, simply “click” in their respective “check” box in the Map Layers column in the left hand side of the PRLIS. Note: only one background layer can be displayed at a time.

How do I change the background to show an aerial photo?
The default background is a basic roads map. To change this to display a high-resolution aerial photo, click on either “Bing Imagery” or “Google Imagery.” These images are updated approximately every 1 to 3 years.

How do I adjust the transparency of particular layers?
You can adjust the transparency of any of the layers and backgrounds in the PRLIS. Adjusting the transparency allows you to see through a layer to other layers or features that may be of interest to you. For example, you can adjust the transparency of the Range Unit layer so you can see what kind of land cover is part of that unit.  To adjust transparency, simply select the layer you want to adjust by clicking on its text label (not the check box) which will highlight the layer. Once selected, use the transparency slider at the bottom of the “Layers” menu on the left hand side of the PRLIS.

How do I use the Landsat TM image to assess the use of my lands?
Even if you aren’t directly managing or utilizing your allotted lands, it’s important to monitor their health. Despite the fact that most allotted lands are leased to non-tribal members by the Bureau of Indian Affairs, it is the responsibility of land owners to enforce the terms of the lease and ensure that the lands are being cared for. Failure to adequately monitor your lands could mean a lowering of their productivity and market value. Landsat TM images are captured each month by an earth orbiting satellite that captures 7 wavelengths of light, some of which are not visible to the human eye, making it possible to filter  reflected light from different types of land cover. For the purpose of the PRLIS, we using a Red, Green, Blue combination of 5, 4, 3.  According to James Quinn at Portland State University, “this combination provides the user with a great amount of information and color contrast. The 5 4 3 combination uses TM 5 which has the most agricultural information. This combination is useful for vegetation studies. Healthy vegetation is bright green and exposed soils are more pink.   The limitations of Landsat TM images are possible cloud cover on the day of the scheduled capture and their relatively low resolution, each pixel equals roughly 30 meters on the ground. Landsat TM images can be helpful for quickly and easily assessing the use and health of your lands however, the only way to be sure is to physically inspect them. We advise that you perform a physical inspection before reporting any possible mismanagement or overgrazing on your lands. If you suspect that the permittee is in violations of the terms of the permit you should contact the Pine Ridge BIA Realty Office at Bureau of Indian Affairs, Branch of Realty, PO Box 1203, Pine Ridge, SD 57770, (605) 867-1001.
