NAPIS® 'Step-by-Step' for creating a NAPIS Map Folder
You may want to print out the NAPIS Site Map description to support this 'Step-by-Step'>. Please contact White Point Systems for additional information on creating region-specific map data layers for use in NAPIS.
Step 1. Open the NAPIS Site Map:
Click on the Vicinity Map on an active Site or Collection data form to open the NAPIS Site Map.
Step 2. Create a New NAPIS Map Folder:
Select Folder | New from the menu-bar to open the Folder Properties dialog shown below. Give the folder a name, such as 'Yunnan'. Do not close the Folder Properties dialog yet.
Step 3. Define the Map Extents:
In the 'Define Extents' box on the Folder Properties dialog use the mouse to draw and define the map extents by holding the left button down and dragging a rectangular shape. This zooms in on the map, setting the map extents for each time you open this map folder. Use the mouse right-click to zoom out on the map box. You may change the extents again later on this Folder Properties dialog or by selecting Folder | Set Extents as Default from the menu-bar. Defining the map extents is important where region-specific projects require that you zoom into the map, especially where GIS backdrop images are used in the map folder.
Step 4. Remove Map Layers used for the 'Default' Map Folder:
On the Folder Properties dialog, highlight a map layer in the 'Layers' list-box and click the 'Remove' button to remove it from your new map folder. Repeat this for all of the default map layers except 'map_data'. The 'Default' map folder includes the following 1:1,000,000 scale map layers:
- World30 - a grid of 30 degree quadrates
- Cntry94 - political boundaries known in 1994
- Rivers - rivers
- Lakes - lakes
- map_data - NAPIS site points entered in the database by the user (this layer can not be removed)
Step 5. Add Map Layers to the New Map Folder:
On the Folder Properties dialog, click 'Add' to open the 'Layer Properties' dialog shown below.
Click the 'Browse' button to the right of the 'File' field and navigate to your project folder. Note the file types supported by NAPIS Map at the bottom of the form below. The file type *.shp is for a Shape File, which is the ESRI file format for vector-based GIS map layers. The file type for geo-referenced backdrop images, like satellite images, is *.tif. Select and highlight a map file by name.
Click 'Open' to return to the 'Layer Properties' dialog.
With the correct file path highlighted on the Layer Properties dialog, set the following properties for your map layer:
- ID Field - default sets to the ID detected for your map layer, but may be modified to select which field to use for the 'Map Tip'
- Type - defaults to the type detected for your map layer, but may be modified
- Style - default sets to solid, but dashed or dotted lines or a combination may be selected
- Color - opens a dialog for selecting the color of your lines or polygon fill
For *.shp files it is important to select a color that will have meaning and distinguish the layer on the map. Click 'OK' to return to the Folder Properties dialog. Repeat Step 5 for each map layer included in your project.
Step 6. Arrange the Map Layer Display Order:
Once all of your map layers have been added to the Folder Properties dialog you need to arrange their order so that images are not covering vector-based layers (thus hiding them from view). Highlight a map layer in the 'Layers' list-box and click the up or down arrows to change the display position.
When you click 'OK' the map will open to the area set in the 'Define Extents' box. Use the Zoom tool to zoom in to the *.tif image. Select Folder | Set Extents as Default from the menu-bar to reset the map extents to the zoomed image. Each time you open this region specific map folder in the future, it will open to the zoomed extent you have selected.
The layer order selected above will display the map below. Note that the roads are displayed on top of the GIS backdrop image.
Zoom and pan to navigate around the map. Note the latitude and longitude position (degrees : minutes : seconds) of the cursor displayed in the lower left corner. The scale-bar displays in units of U.S. miles, as does the measuring tool, and cannot be modified to kilometers or other.
Step 7. Close and Re-Open the Map Folder:
To exit the map select Map | Close from the menu-bar or click on the red back-arrow. When you re-enter the NAPIS Map, the 'Default' map folder may be displayed. To re-open your region specific map folder, select Folder | Open from the menu-bar to call the 'Open Folder' dialog shown below. Highlight your map folder and click 'OK'.
