If your image comes without pre-computed statistics QGIS and ArcGIS will produce a quick estimate of what the ideal min/max for displaying the image is. This does not change the values you are seeing, just the color range. You can easily test this by comparing the pixel values. If you want to see the computed band statistics you can right click on the layer ...

This is a quirk of Esri, it used to be the other way around. By default it will save all customization in only the current document, to change this open the menu customize::customize mode.. Turn off the checks indicated by the arrows to make ArcMap save to your Normal.mxt. Please note that any open instances of ArcMap will write to the normal on exit so ...

The best way to save all of the settings of a layer (or multiple layers) in a map document, is to create a layer package. Select all of the layers you would like to save in the package Right-click one of the selected layers and click Create Layer Package Follow the Layer Package wizard, making sure to fill in all of the entries (such as summary and tags). ...

The way I've always limited what pages are included is through a definition query. If you can't edit the original data, then you could make a copy of it. However, I'm not sure of all your requirements. The script below will make a copy of the original area layer, and add a field called DisplayPage. It then does a SelectByLocation to select all the areas ...

Field calculator expression, Python: def truncate(f, n): s = '{}'.format(f) i, p, d = s.partition('.') return '.'.join([i, (d+'0'*n)[:n]]) To run on x, y and z fields, e.g.: truncate( !POINT_X!,2) Code taken from http://stackoverflow.com/questions/783897/truncating-floats-in-python modified slightly for field calculator Second field calculator ...

I am sure there is a better way but this will work: In the attribute table, create 3 new fields called x, y and z and make the field type "Double" Right mouse click on the X field and calculate its geometry x coordinate Right mouse click on the y field and calculate its geometry for the y coordinate Right mouse click on the z field and calculate its ...

I will assume these catchments are determined by taking into account minimum friction on the transport network, which is generally the travel time and you have ArcGIS Network Analyst extension. The brief process that I can advise as follows: First you need to register an origin for each parcels, namely if there is a building this is going to be the source, ...

I typically, whether on local drive or server, change my options for referencing data to use relative paths. Go to File > Map Document Properties, and check the "Store relative pathnames to data sources" radio button. Save your MXD. This way, if your data moves with your map documents, while keeping the same folder structure, the data sources will remain ...

Here is the a detailed walk through provided by Esri on how to make a story map. Within this site you can navigate around to find different templates and application types with instructions on how to create your own.

Things you may be able to try: -Get a better internet connection to your VPN. -Try running subsets of your records (500/time) --Select 500 records (so they're blue), run the Field Calculator, rinse/repeat -Try not doing it during an edit session (faster but can't revert) -Make sure the VPN is letting you access your license server (if applicable) --You ...

A layer (.lyr) file and your rasters are not the same thing. A layer (.lyr) file is serving two functions: It tells ArcMap where to find the raster data. It tells ArcMap how to draw the raster data. A layer file by itself can be shared between multiple users. When brought into ArcMap, this information is stored in the map document, along with any ...

According to the docs thinning is for line features. Remember to select "area" as the feature type in r.to.vect.

You could use a Spatial Join This will join attributes from one feature class to another based on spatial location.So you can join the RockType attribute to any points that fall inside of the polygons.

Looks okay in QGIS 2.10 pisa There is a lack of attributes only track_id seems to be populated

Depending on your precise requirements, I think layer files, rather than layer packages, may provide you with a better solution. If you right-click on any layer (or layer group) in the Table of Contents and Save as Layer File you have all the Properties of that layer (but NOT its data) stored in a small file that can be easily added to another map. If you ...

I believe this is supported in versions > 10. Open up attribute table Access field properties (right click header)

Using esri streetmap data you can get an idea of how to accomplish multiple zoom levels on 1 layer. You should either have a dvd that came with your product or can download it with your global login at my.esri.com. For example in the transportation layer group they have road with multiple zoom levels. No matter what scale you zoom to one of them turns on. ...

The best way is to use viewshed (observer point does not seem necessary based on you question, except if you want to know which spire can see which WTG). First you determine the locations where you could see your WTG (viewshed of the spires), then you use "extract multivalue to point" to transfer this information from the resulting raster to each WTG point. ...

As a supplement to Brad's answer, there is no setting or option to accomplish this automatically. That being said if this is just a one time operation it can be accomplished in two clicks. Once you have your selection: Right click the layer in the TOC navigate to the 'Selection' menu and click 'Create Layer From Selected Features'. This will create a ...

I recommend becoming familiar with ArcGIS's Data Driven Pages toolbar. Set up a map file to appear as you desire, and then add the DDP toolbar. Click Set Up Data Driven Pages. Update the layer drop-down menu with the layer you wish to iterate through. On the extent tab, you can set a margin (that 'zoom out a tad more' part of what you're after). Once you ...

This can be easily achieved with QGIS (I'm doing this in 2.10) and the Atlas generator. Open up your shapefile in QGIS. Symbolise it as desired. Project>New Print Composer Add a map to the layout that covers the whole page. After the map is added, we need to set it as controlled by atlas (select the map and go into Item properties): Next we set up the ...

A BLOB field is simply a field that stores data in binary. From Wikipedia: A Binary Large OBject (BLOB) is a collection of binary data stored as a single entity in a database management system. Blobs are typically images, audio or other multimedia objects, though sometimes binary executable code is stored as a blob. Database support for blobs is ...

If you have a table joined when you create the field it will automatically add the layer name. If you want to avoid this remove the join then create the field and rejoin the table. Or you could right click the field and change the field alias to remove the layer name.

This how I would do it: Create your two points Cast polygon into ICurve Use the ICurve.QueryPointAndDistance Method and get the DistanceAlongCurve value for each point Use ICurve.GetSubcurve Method to extract the red curve you have identified in your image.

First of all I would strongly recommend that you export your map to either a PDF or an image file and use that to plot. This is especially true for very complex maps with lots of layers, rasters, transparencies, annotations, etc. The Page Print and Setup Dialog has nothing to do with printing. Its sole purpose is to set a physical layout page size of your ...

At this stage (when your legend is fixed), you should convert your legend to graphics, ungroup the component and manually arrange them as you want (there are tools to align and distribute the graphics).

Your input and output column should be text type. It's expecting a string or buffer and you passed probably integer or double.


2

There is an even simpler way to do this, especially if you have a lot of layers in your map, as your method would be a bit time consuming. In the Layout View, right click on your Legend and select "Properties". Go to the "Items" tab and tick the box "Only show classes that are visible in the current map extent" found in the "Map Extent Options" section.

While the previous answer is only temporary while the table is open. It is the only method for changing column colors. Table settings are in the arcmap options dialog. These color settings affect selected rows.

I think spatial join will do this... Set Target as shapefileB, join as shapefileC. Add a numeric field and set the merge rule to count. Match option as INTERSECT. Do you want to count all of the points that land in each buffer circle (the above does this) or only the ring of area between the previous and current? If the latter, you will need to minus ...
