Please run the plugin by choosing "Shp to Obs" from the "Vector" menu.
First, a welcome box appears reminding you of the required input files. Continue by clicking "next".
Now a second window opens. It has got four tabs.

In the "Buildings" tab, the buildings layer is selected. After selecting a layer from the upper dropdown menu, the field containing the height of the buildings can be selected from the lower dropdown menu.

The "Trees (optional)"-tab contains the settings for an optional trees layer. If you want to have trees in your obstacle file, select the corresponding trees layer from the upper dropdown menu. Afterwards you should be able to set the fields for the tree's attributes in the lower section.

The third tab is the "Center Point(s)"-tab. The center points layer can be selected from the upper dropdown menu. Afterwards the the field setting the vertical offset of the center points can be chosen by the lower dropdown.

In the "Output Directory"-tab the folder and file name of the new obstacle file(s) is set. If you saved a qgis-project previously, name and path of the project file are proposed.

After selecting the required layers and fields, and entering path and file name, click the "Convert" button to start the converter. According to number and complexity of your input geometries the process may take some time.

The Shp to Obs plugin needs at least two input files loaded in QGIS (since version 0.1.6 it can be run with a buildings file alone using the layer center as a center point) to create a RayMan obstacle file. All of the required files have to be shape files.
Please make sure all the desired files are in the same metric projection (e.g. UMT, or GK). Degree coordinate systems won't work as RayMan needs the distances in meters.

Buildings file (required): First, a polygon shape file is required, that contains the buildings for the .obs. It needs a field in the attribute table stating the height of each building. This field must not contain any missing values.

Center points file (optional for version >= 0.1.6): Second, a point shape file is required, setting the center point(s) of the .obs file to create. If this layer consists of several points, Shp to Obs will create an obstacle file for each of the points. The center points input layer requires a field in the attribute table, that specifies the vertical offset of each point. A negative value in this field will increase the height of all obstacles, while a positive value will reduce the height respectively. Zero means no offset. This field must not contain missing values.

Trees file (optional): Optionally, Shp to Obs is able to include trees into the obstacle file. Therefore a third input layer is necessary. The trees layer has to be a point shape layer and must possess at least the following five fields, that, again, must not have missing values.

? A height field specifying the total height of the tree (in m).
? A crown radius field, that gives the radius of the crown expansion (in m).
? A trunk height field that sets the distance between the ground and the lower side of the crown (in m).
? A trunk radius field setting the radius of the trunk (in m).
? A type field specifying the type of the tree (1 char in small letters, "l" for a leaf tree, or "n" for a coniferous tree).

Dear *,

please first create a post in this forum and give us a few days to reply.

If there is no response to your post for some days, please do not wait forever, but send a personal message (may be empty) to the admin user "dominik_mif". If there is still no reply, please send a notification to "dominik_froe/at/web.de" (replace /at/ by @!).

In general, I should get a notification as soon as there is a new post, but this obviously did not work in the past. I apologize for this!

Thank you!

Best regards,
Dominik

Dear Sr.

I´d have difficult in put datafile in programe Rayman. Can somebody tell me how do it?

Thank you
