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 ...

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. ...

In the sub model, insert "Collect Values" after the iterator. You find it in the model builder menu "Insert" -> "Model Only Tools"

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

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.

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.

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 ...

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 ...

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 ...

check out AnimatedCluster strategy for OpenLayers here for big data and good ui. you can find code example here. beside this examine openlayers clustering example. Cluster Strategy Example, here Extended clustering, here i hope it helps you...

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 ...

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.

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.

You can just drag&drop your already built model into the new model

Step one: Make a model Step two: Search for "Raster Calculator" in the search window (usually on the left side of the ArcMap Window) Step three: drag the tool into the model builder box Step four: double-click the tool and input your equations Bonus: Use the Iterate function to loop through multiple rasters

I'm sure that smarter people that I will have better answers.... But an idea is to create raster surfaces from the contours, as this may afford easier comparisons between the different models, and the overlapping nature of the data.

This is a job for the Dissolve tool.

I would start by importing all the data into PostgreSQL with the Postgis extension. Using shp2pgsql would be the easiest way. Make sure you include the proper flags to generate indexes on the data. After importing the data, you'll probably have to massage the date/times from varchar to timestamp. After you get all your data imported, you can use the ...

There is a tutorial here that will walk you through the process step by step. If you do not use Python, you may be able to translate the tutorial's workflow to a model in ArcMap. # Author: John Speargas # Import module import os # Input folder containing files to be renamed folder = “C:\\GIS\\TEST\\directory_to_be_renamed\\” # Input lookup table ...

You could store the non-measured Z values as 'nan'::float8. For example: SELECT ST_AsText(g), ST_X(g), ST_Y(g), ST_Z(g), ST_Z(g) <> 'nan'::float8 AS has_z FROM ( SELECT ST_MakePoint(1, 2, 'nan'::float8) AS g UNION SELECT ST_MakePoint(4, 5, 6) AS g ) AS f; st_astext | st_x | st_y | st_z | has_z ...

Create a secondary geometry column with three dimensions to hold the vertexes of linestring that has the three-ordinate( triple ) values. For this schema to work the following assumptions are asssumed: the linestring is valid, it does not contains duplicated points geometries are linestrings there must be at least two vertexes with 3d coordinates into a ...

Rsquared should not be used to compare models. Use log likihood or AIC values. If your residuals in GWR are random, or I guess appear to be random (not statistically sig.) than you might have a specified model. It at least suggests that you don't have correlated residuals and should suggest that you do not have any omitted variables.
