mmm LBCS Codes<\/figcaption><\/figure>\n

This is duplicate post of a discussion I started on ESRI\u2019s CityEngine support forum<\/a><\/strong><\/p>\n

Since my first post has produced such an amazing response\u00a0<\/a>\u00a0I shall continue and start a thread on using GIS data on landuses.<\/p>\n

What I have been doing is using my road network in ArcGIS and importing it into CityEngine where I make a suitable road network, this I use to create blocks that are\u00a0not<\/strong>\u00a0sub-divided. \u00a0 I then export these block shapes as a shapefile back into ArcGIS where I add new fields (like an LBCS or landuse Code<\/a>). \u00a0 I can then make an outline landuse plan from these in ArcGIS and symbolise them.<\/p>\n

So we start back again in CityEngine with some static shapes with an object attribute for the landuse (in my case I’ve called it LBCSCode).<\/p>\n

The layer attributes code would look like this :<\/p>\n

attr landuse = getObjectAttr(\"LBCS_Code\")<\/pre>\n
Then to colour the static shapes I could use the following code (don’t forget to apply the rule file!):<\/p>\n
attr landuse = \"0\" \/\/ this just\u00a0initialises\u00a0the attribute that we have in our layer attributes\r\n
Lot--> \u00a0\/\/I didn't use LotInner as this example doesn't create a subdivision<\/div>\r\n
\r\n
case landuse == \"1000\" : color(\"#FFFF00\") report(\"1000\", geometry.area())<\/div>\r\n
case landuse == \"2000\" : color(\"#FF0000\") report(\"2000\", geometry.area())<\/div>\r\n
case landuse == \"3000\" : color(\"#A020F0\") report(\"3000\", geometry.area())<\/div>\r\n
case landuse == \"4000\" : color(\"#0000FF\") report(\"4000\", geometry.area())<\/div>\r\n
case landuse == \"5000\" : color(\"#BEBEBE\") report(\"5000\", geometry.area())<\/div>\r\n
case landuse == \"6000\" : color(\"#2F4F4F\") report(\"6000\", geometry.area())<\/div>\r\n
case landuse == \"7000\" : color(\"#90EE90\") report(\"7000\", geometry.area())<\/div>\r\n
case landuse == \"8000\" : color(\"#228B22\") report(\"8000\", geometry.area())<\/div>\r\n
case landuse == \"9000\" : color(\"#FFFFFF\") report(\"9000\", geometry.area())<\/div>\r\n
else : color(\"#000000\")<\/div>\r\n
<\/div>\r\n<\/div><\/pre>\n
You can also see that I’ve used the report operation to produce a summary of the land areas (helpful when doing landuse plans!)<\/p>\n
\"\"<\/a>
Lovely reporting!<\/figcaption><\/figure>\n
So would anyone do this differently? \u00a0Thoughts\/suggestions\/corrections?<\/p>\n
The next post will cover using this static shape layer to inform a dynamic model so change landuses in the object attributes here will change what happens in the dynamic model.<\/p>\n","protected":false},"excerpt":{"rendered":"
