Methodology

Data Sources: Three data were used for this final project.

LandUse2011_shp.zip ;  Community_center_shp.zip ;  Zoning_districts_shp.zip.

Data processing+preparation:

Below is a table showing where and how data was transported for this project. Many of data cannot use directly in TerrSet because they almost are SHP File data, so it was necessary to converting shp to raster or vector data.

Dataset Name	Format	Source	Use
LandUse2011	.shp to rst	Open data Vancouver website	Reclass, project, overlay
community_center	.shp to rst	Open data Vancouver website	Reclass, buffer, project, overlay
zoning_districts	.shp to vct	Data Warehouse from SIS Data (S:)	Shapeidr

methodology: 

Opening LandUse2011 in ArcMap, and it was a polygon. For converting first it to raster data, using Polygon to Raster. Then, the LandUse2011_raster was produced. After that, using Raster to ASCII saved as TXT document. Finally, open ArcRaster tool in TerrSet for transform the TXT document to Raster data, which was for allowing the data can open successfully in TerrSet. The same way did for Community_center, but using Point to Raster at first step because it was point.

 

For this project, only the commercial area of land use was required, so in ArcMap, the Layer Properties need to used, selecting ‘Municipal=City of Vancouver’ and using Selected by Attributes selected ‘LU_CodeDes=Commercial’. Then, transported it to TerrSet. The raster data of commercial area below:

After these two image were permitted to open in TerrSet, the first thing was use RECLASS tool for collecting all values into two class: 0 for no data, 1 for area that have data value.

Then, creating BUFFER for community center data, using community as feature image and set the buffer width was 100 meters. This 100 meters areas were the suitable areas for building public gardens around community center. As the image below:

Finally, for overlay the commercial area and community buffer, PROJECT tool was required. There was an attention, making sure the columns and rows in these two images were the same. Columns=487, rows=434. The columns and rows were the same numbers and these two images would be allowed to overlay. After this step done, the two outputs for commercial and community, which were displayed the same appearance as their reclassed images. Below is the example of commercial one:
