Hi, maybe this goes to @djordje. I tried to extract a part of Doha, Qatar. Because of the rapid developed settlements, I figured out that gismo gave me older situations, where many buildings are missing. Because of openstreetmap.org has the latest situation implemented, I am not sure why gismo gave me old building-, terrain- and street situations.
Maybe someone knows the way how to use the latest maps?
Gismo downloads an openstreetmap data, and then after that uses the same downloaded data.
In order to force it to get the latest data from openstreetmap, delete the folder from C:\gismo\osm_files. The folder would be named the same as your _location.
If you don’t know which folder it is, just delete all folder’s with “Doha” in their name at C:\gismo\osm_files.
Just don’t use MapWinGIS 5 and newer. There have been some API changes with this versions, that Gismo didn’t adapt to, yet.
For current components, you can use any of the 22.214.171.124 to 126.96.36.199. My recommendation would be 188.8.131.52, as plenty of testing was performed with that exact version.
What is the issue with unblocked downloads?
If you unblock the initial .zip file, then neither of the Gismo component files will be blocked.
With terrain - it is the same as with openstreetmap: Gismo will download a terrain data, and use it. If you would like to have an updated version, you have to delete the file (corresponding to your location name) in C:\gismo\terrain_files folder. Still I wouldn’t do that, as terrain data probably hasn’t been changed. With openstreetmap it can happen, as their database is constantly changing each day.
Openstreetmap depends on the contribution of users to add data.
You can be one of those, and add the outlines of the missing buildings. Here is a small tutorial showing how to add information about building stories or height.
The other solution would be to import a shapefile of Doha by using some other plugin, like Elk for example. The problem may be that a lot of free shapefiles that you will find online, are actually created from openstreetmap data.
Maybe you can ask/send them an email, if Doha’s local municipality has such a file, and if they share it with public.
Can you tell me which kind of shapefile I should ask for. Does the Shapefile safe any kind of data like streets, buildings, etc. or will it become necessary to get mutiple shapefiles for each aspect (like streets, buildings, etc).
Morover I am not sure how to import the shapefile into gismo.
It seems I was wrong. Elk does not have a shapefile importer but Heron.
Here is small youtube video:
Sometimes shapefiles can include both the buildings and street axes, or they can be separated.
I took a look at your link, I couldn’t find any map containing building outlines.
And even if there are, you can not export them - they allow only SVG vector export type.
This file format is not georeferenced, meaning you will not be able to correctly position the building outlines in Rhino, in case you want to use a terrain as well.
Your problem is not an easy one to solve. It quite often happens that you can not get very precise GIS data for free.
Gismo sort of has it as well, but not as a separate component - as a part of a “OSM shapes” component.
I have been thinking of creating a new “Import Shapefile” component for some time, as only the component icon is missing. However, this may open a plethora of user questions when it comes to coordinate reference systems (“Why doesn’t my imported shape file allign with Gismo terrain, or Gismo openstreetmap data…”).
When you open any of the maps, in the top right corner, there is a “Print” option.
But it seems I was wrong again: psaqatar.maps.arcgis.com SVG export does contain georeference location data:
