I think the fishnet tool is the best solution. The polygon to be split can be given as template. This will ensure that the resultant grid is within the required polygon boundary. any suggestions ---

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).

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 ...

In ArcGIS... Let's say you have polygons and lines such as in the example below: Perform a feature to line, with the polygons and the lines as your input. This slices the polygons by the lines. Select all the features on one side of the line. Export selected features. Turn off all layers except the new layer. Select the 'slivers'. Perform ...

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 ...

We have similar problems with the geo atabases on NAS. In our case it mainly depends on if several people work at the same time with the same geodatabase. Normally it helps to delete manually all lock files and actualize the database by a right click and refresh (F5) If that's not helping it usually the last step is a restart of ArcGIS. Still we ...

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.

A simple method is: mean pixel value * total number of pixels The source tab in layer properties has all the information you need for this calculation.

http://gislab.net/pics/3.jpg This is what you need to do i believe, right click on the map part you created (not the margins Arc wants to put the map in) then goto distribute, then goto fit to margins. This will make your map fit the margins of your layout choice. I would have put in comments, but it wouldnt let me

Fix this by by converting the dbf into a "dbf 4" file (on foxpro) and the warning will not occur.

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.

I came up with another workaround: Copy the whole layer in question. Set it to display at all zoom layers, but set its symbology settings so that i does not display anything at all (for instance, in the Symbol Selector, click edit symbol and then pick a blank Character Marker). But keep the display settings for selected features (specified on the Selected ...

I once used Arc Crawler (or MXD Crawler) that could maybe answer your question but I couldn't make it work again on my Arcgis 10.X version. Seems to work for ArcGIS 9.3

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 ...

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 ...

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 ...

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 ...

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. ...

This isn't a step-by-step answer, more of an explore-on-your-own answer. To get your LatLon data into XY coordinates, you would want to "Display XY" the excel table and save the event layer as a feature class. After that, there are several options you'll want to explore. There's a tool in ET GeoWizard called "Points To Pie Segments" that may be useful to ...

Searching Google for "tnc disturbance" led me to another copy of the same post at https://geoapplications.wordpress.com/about-2/tnc-land-disturbance-editor-arcmap-custom-add-in/ where it says: For more information about the Add-in please contact John Donoghue at: mail [at] johndonoghue [dot] net.

I have found that I need to go into the environments and specify that the processing extent is the extent of the shape file in question. For some reason the default extent is off.

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. ...

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

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 ...

"Extract value to point" will extract the cell values for each point. If you want to remove duplicate points (several points in one cell), you could compute the row and column values of each point in the coordiante system of the grid cell, then you can identify duplicate entries (using "Find identical"). for the corresponding row/column values, take the X ...

You should be able to simply add your EPSG:32649 image to a data frame that has its coordinate system already set to EPSG:4326. On-the-fly projection should take care of displaying it in the correct location. If you need to set a transformation, then doing this should trigger a warning for you to do so.

I would suggest a raster-based cost allocation method of creating catchment areas. The output might look something like this: You would require a cost surface, which when creating the cost surface, would allow you to accomodate all the input parameters you specified above: buildings as a separate layer should be burned into your cost surface at a much ...

I use a very simple method for this: Open the source MXD (containing the layer to be copied). Open the target MXD (where the layer should be copied to). Drag and drop the layer from the Table of Contents in the source MXD to the Table of Contents in the target MXD. All of the properties of the layer (properties, style, labeling, path of source data, ...

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 ...

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

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 ...

Thanks Mapperz! I converted the GPX file in QGIS to a shapefile and imported that in arcmap, looks great now. Suppose the Arcmap in-program GPX to Shape converter doesn't work flawless still..

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 ...

Here is a list of all of the Keyboard Shortcuts and Tips that is provided with ArcGIS for Desktop. It looks like pressing spacebar while you have the layer selected will turn it off, and then pressing it again will turn it back on. This way you are free to roam the map and toggle the layer.

The second answer of KevonFredrico worked well for me. With the BasicHttpBinding object you can indicate extra properties that are specified in your app.config like TransferMode or SendTimeout: binding.TransferMode = TransferMode.Streamed; binding.SendTimeout = new TimeSpan(0,10,0); //10 minutes

After you have done the Spatial Join as was already mentioned you can make a selection of the points will a value and field calculate the data from your polygon. Make sure your fields match and will accept your bulk data load.

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.

It seems that you final goal is to total raster values for each vector polygon. It's worth pointing out that the GRASS module v.rast.stats does just that.

With a dynamic map service, you can simply request it in a different coordinate system using the spatialreference parameter. Lets assume you already have a map defined in your javascript app, with a spatial reference of 4326 (web mercator), by simply adding the dynamic map service, (with a differing supported spatial reference) it will automatically ...

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 ...

Thanks again @FelixIP, and I'd like to post my new answer Here, the independent variables include slope, elevation, precipitation,distance to roads, and distance to river, and all values are 0 to 100 after doing normalization. For normalization all the values to a range of 0 to 100, I used the Raster calculator tool in ArcMap 10.1 with this equation: ...

On second thought I decided to post my answer. Normalising variables, which solved an issue is not exactly GIS thing, however careful spatial variables selection for regression analysis is. I'd suggest caution with that many independent variables, because some of them aren't really independent, e.g. distance from 'river' and terrain slope. I've made a ...
