8.2.10 Other Tools

Level of expertise required for this Chapter: Intermediate; specifically for LUPMIS @ TCPD

Following functions are available:

• Overlay
  

This is the preferred option to overlay polygons. (Do not use the Map Maker-inbuilt option). Press 'Start' and the next menu will show:

You first select the file / files to overlay (1), then run (2) and save the output (3). Be aware, that styles are not maintained.

This is also the fastest way to solve topology problems, related to polygon islands and multiple partly overlaying polygons.

See also example of street polygon overlay in Chapter 8.2.

• Check topology
  

This Tool check the GIS topology of a DRA file.

• Export z-values
  

You can convert a DRA file with z value, such as altitude or ..., to Excel for a 3-dimensional display in Excel (conversion of a file from raster with z values to a CSV file for import to Excel).

Technical Note 1: As requirement, the raster must be a complete matrix, with x and y values to be identical for each cell.

Technical Note 2: To create XYZ file from a line (contour) map, in Map Maker:
1. Prepare contour line map in Map Maker, with altitude in meters (numeric) in Display Labels
2. Utilities > 3D surface utilities > Create surface > from Contours > Select polygon DRA file > Settings > Save as DEM
3. Utilities > 3D surface utilities > Export surface > Surfer (xyz) > ...

• AutoCAD
  

Because AutoCAD is not a GIS program, its drawings can not be imported directly into Map Maker. Conditions are not met (georeferencing, projection, polygon topology, snapping, layer structure).

Steps to import an AutoCAD map / layer into Map Maker are as described below. For full functionality, you must have 'Teigha' installed on your computer (available on LUPMIS Installation CD), and Map Maker configured for War Office.

1. Convert the DWG or DXF file into DXF file with format ASCI2000: Use the freeware Teigha.
2. Import the DXF file with selected layer to Map Maker: Vector Utilities > Import files > DXF
3. Check the projection. If it is in UTM 30, the process is complete.
3a. If the projection is in War Office feet, convert the file it from War Office feet to War Office meters: Live layer > Transformations > Convert feet to meters, and continue with the next step.
3b. If the projection is in War Office meters, convert the file from War Office to UTM 30: Latitude and longitude utilities > XY file to another projection.

See more explanations in Chapter 5.4.3.

For the transfer of planning data to the application of architectural design, it is useful to convert the planning GIS map or an individual parcel to AutoCAD through Utilities > Vector utilities > Export files > to DXF. You can then use AutoCAD for architectural design work.

• Calculate shifting
  

• Import kml
  

- Soon to be explained here -

• Download and Import OSM
  

Open Street Map (OSM) is a fast growing standard of open-source GIS data. With this Tool you can download OSM files and automatically converted them from lat/long to UTM. This Tool will access the OpenStreetMap online GIS database (through their API) and download all features for the defined area.

With the LUPMIS Drawing Tools: Import kml/osm [1] > Download and import OSM [2] >

Define the area with minimum and maximum x and y [3]. OpenStreetMap limits the area to a maximum of 50 km, but also the number of features (currently, 50,000). If the area defined is too large or there are too many features, a message will tell you to decrease the size.
In the sample below, we are interested in all streets with their streetnames [4]:

'Continue' [5] to run the process, which might take a while for the download.

If you import street names, be aware, this is open-source data - not official. It is the Assembly which has the authority to define street names, not Google or a contributor to OpenStreetMap.

The result is a DRA line file, if selected with streetnames, from OpenStreetMap (very similar to Google data):

An alternative approach, if you already have the OSM file or want to download it directly from the Internet, is the 'Import OSM' option:
www.openstreetmap.com: Export [1] > Define the area of interest by zooming, paning or by lat/long figures in the entry box [2] > Export [3} > Define location and file name on your computer.

If the 'Export' button [3] does not appear or 'File not found', define a smaller area of interest, and repeat.

• Altitude
  

- Soon to be explained here -

• Unit Conversion
  

You can convert units in many different ways. One part covers conversions between projections.

A training video shows the conversion of one point from UTM 31 to UTM 30 and its display in the GIS (in YouTube).

• Procedure: Local Plan
  

• Photo / topo coverage
  

• Clean temp file

• Change district
  

If you set up a new District (or Region), you should follow a sequence of data population procedures: See Annex 9.1.
