Locating Suitable Regions for Tigers in Thailand

Goal

Your assignment will be to use datasets of information relating to tigers in Thailand.  The government has set aside environmentally protected areas throughout the country. You will find the protected areas that have the best environment to support tigers.

Objectives

 

1.         The protected area must contain, at least in part, any of the following vegetation types: Dipterocarp, Evergreen, Mixed Deciduous, Non-Forest, Pine Forest.

 

2.         The protected area cannot be within one kilometer of a road.

 

3.         The protected area must have the following combination of preys: either Sambar or Eld_deer, and Guar with a value not more than one. (Caution: Gaur must be in the protected area).

 

4.                  The roundness of the protected area(s) is less than 1800 (roundness = the ratio of the area to the perimeter or area/perimeter).

 

Undergraduates: Complete the first three objectives.  MA's and PhDs: Complete all four conditions.


Data

 

The data are in the format of an ArcView project file for you to practice importing a project into an ArcView8 map document.  The following data are provided in the lab1.apr: boundary.shp, forest.shp, road.shp, protect.shp, lmammal.dbf, and legend1.avl.  You can locate lab1 data on u://scratch//gtechgisII_fall02/labs/lab1.

 

Methods

 

Note: complete each objective in the order that it is given. 

 

Save the data for Lab1 on your drive (i.e. u://name/GISII//Labs/Lab1

 

1.         Importing lab1.apr into an ArcMap map document (note: this project does not have a layout).
 

                        Open ArcMap.

                        In ArcMap, from the File menu, choose Import from ArcView project.

                        Click the Browse button and navigate to the folder where you downloaded the lab1.apr.

                        Click on view1 and Open.

 

2.                  Investigating the new map document

 

Open ArcCatalog.

Click on each .shp file in the Lab1 folder and investigate the the Contents, Preview (Geography and Tables), and Metadata.

 

In ArcMap, notice that there is one View in the Table of Contents.

Click on one layer at a time – select the file in ArcCatalog – and view the layer in the Data frame.

 

Check the projection of your layers by clicking on View/Data Frame Properties/Coordinate System.

Notice that your data layers are in an ‘unknown’ coordinate system (in ArcView3.2 this data would be labled as decimal degrees).  Another way to examine your coordinate system is to move your mouse across the Data frame and notice the numbers changing along the bottom bar.  Note that these numbers represent an ‘unknown’ coordinate system. 

 

For this lab DO NOT set the projection.

However, you will need to set units for the view.  Click on View/Data Frame Properties and General/ Units – assign both Map and Display units to ‘meters.’

 

Review goal and objectives for Lab1.

 

3.         Begin the analysis

 

            The applications that you will need for this lab are ArcMap and ArcCataglog.

           

 

                        Hints:

 

            Refresh your memories on how to utilize Geoprocessing tasks (i.e. queries, buffers, and/or clips, etc.) 

                        The ESRI tutorial ‘Explore ArcMap and ArcCatalog’ is helpful.

To determine roundness: calculate by using the data obtained from your queries.  


Post your final map on your website under GISII with a link to Lab1. 

 

Please write the sequence of commands used to produce your map.
