The "export to Python" option in the modeler has been taken out in the latest version. The modeler has been rewritten and there was not enough time to implement this feature. We have released the new version without it, considering that the improvements that this new modeler have are really worth it. The "export to Python" version will be available again in ...

What these procedures are Although OLS and GWR share many aspects of their statistical formulation, they are used for different purposes: OLS formally models a global relationship of a particular sort. In its simplest form, each record (or case) in the dataset consists of a value, x, set by the experimenter (often called an "independent variable"), and ...

It seems you are doing research. Here are some advices: Ask the domain experts: if you ask from an expert about the exploratory variables, he/she can easily filter many of the variables due to their irrelevancy to the response. If you don't have access to an expert, then review the literature. Use PCA (principal component analysis): PCA is a type of ...

Within the raster calculator plugin you would subtract one file from the other. DTM - DSM. This will give you a new file that would be just the canopy.

You have to make it ModelParameter see pics. And then you can add this variable in first model.

Looking at your model, here is what I suggest you do to make your model perform the way you are expecting it to. Your model should be built in the following order: Instead of the "Select" too, use the "Make Feature Layer" tool. Not only will this allow you to use a Featureclass (from disk, not ArcMap TOC) or a Layer (from ArcMap TOC), you can also apply ...

You need to create a Sub model that does the "clipping" and call this from within Master model. Your sub model must expose the output of the collects tool as a parameter. I think you want to do an Intersect not actually a clip as you need to pass over the polygon ID to dissolve the road network. So the sub model (what I am calling the clip model) would ...

You should also try Open Meteo Foundation API. It covers all Europe On the same web site, you can also get raw data for forecast using their server. The licence is really open e.g https://openmeteoforecast.org/wiki/License

If you're looking for an ArcGIS solution and you have a bldg footprint polygon layer as your pic indicates, then it may be relatively straightforward to: 1- Perform a spatial join, parcels (source) to bldgs (target) so that your bldgs layer will 'inherit' the parcel IDs of your parcel layer. 2- Add a new numeric field for which to calculate the bld nos. ...

This falls within the field of linear referencing. The spatial feature is represented typically as a single "centerline" and non-spatial records/elements are used to record attributes along that centerline with start and end measures. I see ISO does have a published specification. ISO ...

@dhollema is guiding you to the right direction and fortunately it seems GML supports this data type. Note that LRS(Linear Referencing) is designed and developed for this specific type of applications. The first reason to use LRS is that Many organizations collect data about linear features as point locations along the line as an alternative to expressing ...

Stepwise regression is generally an unwise approach, even though commonly used and published. For supported inference, evaluating model support and model fit, the canned ArcGIS tools are not a good platform for specifying a statistical model. A one-size fits all approach to fitting regression models is never a good idea. The message regarding the foibles ...

You've only referenced the model, not called it. In short, add () to the end of the call. So in your case: arcpy.Workshopmodel_TestAlias(). At a simple level, your model is a method, not a variable. However, this will only work if you're model doesn't have required parameters, or if all required parameters have default values (you specified values in the ...

The techniques to solve your issue and improve vector web mapping are: Generalisation: The objects to display should be simplified/aggregated in order to adapt their level of detail to the visualisation scale/zoom. In theory, there should be on data layer for each zoom level. The best is to use a multi-scale database. See this question for an overview of ...

This is a job for the Dissolve tool.

Ground water modelling is generally not visualized within what most people would consider to be GIS software. The more common term in the field is simulation software. Now, the software you would use would very much depend on exactly what you are trying to do. For example, you might use MODFLOW (USGS) to solve the advection-dispersion equation and MT3D for ...

There are many ways. You could for example compare the ratios of the mutual area and the diffrence. Or you could check the Hausdorff distance of the polygons. Probably you should combine the two.

You can generate your own wms using the Met Office (UK) DataPoint API "DataPoint is a way of accessing freely available Met Office data feeds in a format that is suitable for application developers. It is aimed at professionals, the scientific community and student or amateur developers, in fact anyone looking to re-use Met Office data within ...

Your grid is not made of polygons. I suspect its lines. Check the "geometry type" section of the metadata section of the layer properties. I'll wager its not "Polygon"... If you made it with the "Vector Grid" tool then you should have ticked "Output grid as polygons" instead of "Output grid as lines".

To build the boreholes, I would recommend this tool which is intended to be used with the 3D Analyst extension of ArcGIS for Desktop: You can set the coordinates of the starting points, azimuth and tilt of the borehole, the depth of the layers interfaces, a water level and some related data through bar charts parallel to the borehole axis. ...

You don't need a specific add-on programme, look at The Subsurface Geology of Brussels, Belgium, Is Modeled with 3D GIS with 3D Analyst. or Modeling the Terrain Below (3D Borehole tools)

You need a subtle change to your model. See the image below: Configure Expression parameter of Calculate Value like this: Set Output Dataset or FeatureClass parameter of Project tool to %output_value%

Geodatabase feature class (and raster, etc.) naming rules: Names must begin with a letter, not a number or special character such as an asterisk (*) or percent sign (%). Names should not contain spaces. If you have a two-part name for your table or feature class, connect the words with an underscore (_), for example, garbage_routes. Names should not ...

I would add the constraint in a migration. Or, in something more pretty: a custom field. https://docs.djangoproject.com/en/1.6/howto/custom-model-fields/#writing-a-field-subclass Good luck.

I think you need to look into using model builder's in-line variable substitution properties to accomplish this. You can get info about that here http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Examples_of_inline_model_variable_substitution/002w0000005w000000/ (I've included a link to the v 10.0 help as I don't know the version you're using ...

The Advanced Python Field Calculator works. The Syntax is a bit diffrent but value = $id should work.

I think I can answer my own question. It might be a bug. In searching on the internet, I found this link: http://hub.qgis.org/issues/9317 where someone is having a similar issue using OTB band math in QGIS version 2 via sextante. It says in the link that this is apparently only a problem for 64 bit versions. I had version 2.2 which does not have ...

you can select specific features with search cursors http://help.arcgis.com/de/arcgisdesktop/10.0/help/index.html#//000v00000039000000 and you can specifiy the input with GetParameterAsText http://help.arcgis.com/de/arcgisdesktop/10.0/help/index.html#//000v00000014000000

I think you are looking for something like http://openweathermap.org/Maps?zoom=10&lat=51&lon=7&layers=B0TTTFFT which also provides a Server API for accessing the data. http://www.wetterpool.de also combines and displays a lot of European weather information. I guess you have to understand German to benefit from that.
