Any old video card will work for the 2D display functions. The video card's 3D capabilities only come into play when using specific 3D GIS features such as ArcScene or ArcGlobe in ArcGIS Desktop. If you aren't planning on doing 3D visualization then it does not matter one bit. I would spend the extra money on an SSD instead.
Right click on the mxd in ArcCatalog, click on Set data sources, and bulk change from there. However, this tool warns: Note: this dialog is intended primarily for preparing map documents for publication. Customizations (VBA code, UI Controls and custom toolbars), graphs, and table window appearance properties are removed from .mxd files when you update ...
A quick and dirty method is to draw the shadows of the building roofs only, render them in dark gray (preferably semi-transparent if there are any underlying ground layers), and draw the building polygons over them. The roof shadows are obtained by translating the building polygons by the distances determined by the building heights in the direction ...
You can use basemap layers to solve this. Once you are happy with the symbology of your layers you can right click the data frame and select New Basemap Layer (see below) which is similar to a group layer. You can then drop the layers into this group, it will redraw them once and then 'store' this view rather than redrawing every time you make a change. If ...
I have found that not all tools work when your geoprocessing environment is set to run in the background. I believe that Dissolve may be one of these. Change you GP environment to Disable Background Processing and then give it a try. I have not tested this but may be worth a try
A few suggestions: Add a thin white border to your inset map, to separate it from the main map. In your example, the thin black line doesn't do enough to differentiate the inset from the main map: When adding leader lines from the inset map to the inset frame (which shows the extents of the inset map on the main map), do it in Layout view and make ...
From the GDAL manual: A merge of two shapefiles 'file1.shp' and 'file2.shp' into a new file 'file_merged.shp' is performed like this: % ogr2ogr file_merged.shp file1.shp % ogr2ogr -update -append file_merged.shp file2.shp -nln file_merged The second command is opening file_merged.shp in update mode, and trying to find existing layers and append the ...
I've seen similar complaints on the Esri discussion forums and a quick search turned up this thread. Some suggestions: Save a copy of the mxd Open the geoprocessing results window and delete the history Under geoprocessing options, results management, change the value to a day or two
Use the Erase (Analysis) Tool:
If you are using ArcGIS 10, then you can directly connect to the PostGIS Data using a Query layer, there is more information on this available here http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00s500000032000000.htm ** good to note this page does not view correctly in Chrome, so I have used IE to read
Use Bilinear Interpolation resampling during display You can somewhat improve the display by changing the resampling method used from the default Nearest Neighbor to Bilinear Interpolation. Layer Properties -> Display Tab -> Resample during display using: Bilinear Interpolation. This effect works best with DEM and the default black and white color ramp. ...
Use the "Feature Vertices To Points" tool within ArcToolbox or if you do not have ArcInfo license then you could use the Polygon to Point tool from ET Geowizard (free tool), then in ArcMap you can use the "Add XY Coordinates" tool to get the XY value for each vertex.
In the Table of Contents window, there is a button across top titled "List By Selection". Clicking this button toggles the Table of Contents into a mode that lets you change the selectablity of each layer in your dataframe.
We need to bear in mind that these data are samples of discrete lithologic domains. Often, the boundary between two such domains cannot be identified in the field and so it's not valid to expect that many of the sample locations will lie precisely along boundaries. A correct solution will be a partition of the study area and each polygon within that ...
If you look on the Labeling Toolbar, there is a Pause button () that acts as a toggle for ALL labels.
You are correct that distortions in the projection can bias flow direction (and flow accumulation) estimates. (Using "unprojected" data is tantamount to using the highly distorting Plate Carree projection.) For merely delineating basins, though, there actually is little problem: although the flow directions and flow amounts will be wrong, the projection ...
The easiest way to do this is to add a new integer field to the attribute table of the parcels layer. Then, run field calculator with the following expression: !Shape!.pointCount-!Shape!.partCount The !Shape!.pointCount returns the total number of vertices in the feature. However, the first vertex of each part is repeated at the end, in order to close the ...
In ArcGIS Desktop 9.3.1 and prior, right-click on the tool in ArcToolbox and select Edit Documentation. At version 10 it is a little bit different, this thread on Esri Support describes the issue: http://forums.arcgis.com/threads/405-Beta-10-ArcToolbox-Documentation Specifically, at 10.0, you need to access the toolbox item from the Catalog window within ...
Tested with a shapefile. 1 Right-click on the layer in ArcMap 2 Select Properties, then the Field tab 3 Select the All fields Off icon, which is beneath the General Tab 4 Toggle back on the fields that you want to keep (I am assuming that you have less fields to toggle back on than to toggle off) 5 Click OK, 6 Right-click back on the layer and ...
I used to benchmark cards against ArcView performance 10-15 years ago. A decent 2D card would perform at least as well as the high-end 3D cards, exactly as expected: panning and zooming around in a map doesn't use the 3D capability. I don't think this has changed any. (Two years ago, when fine-tuning a new workstation, I benchmarked the low-end Nvidia NVS ...
I have found that in 10.0 Field Calculator is quite weird. But I've managed to get it work. The main idea is to enclose field name with single quotes. Example. let suppose we have fields text1 and text2. Rather than Calculating field text2 with expression !text1!, which probably will fail, try this one: '!text1'. As you see I am using single quotes here. ...
I like keeping them simple in regards to the outline and leader line. Below are two examples of Key Maps, though not Insets they show two things that can be done to enhance the readability of yours. 1) In yours, you have two leaders (which would look better if attached to the corners), try to reduce them to one: The red square is the extent indicator for ...
After your grab the TOC, you should see a translucent blue rectangle that represents the new location of the TOC. Drag your cursor over to the left arrow/chevron (either one). The translucent rectangle will change size to show its docked position. Release, and the window should be docked.
On the Table of Contents pane just below the words "Table of Contents" there should be 5 buttons. Ensure that you are on the first button called "List by Drawing Order". This mode allows you to do the dragging that you want.
Your screen capture shows nicely how to copy current cell value to the clipboard. To copy selected records, right-click on the left-most gray button (where the 'triangle' is shown in your screen capture) and choose Copy Selected. Note: keyboard shortcut for both is Ctrl + Shift + C.
Yes, it is possible. Before you can add a feature class you need to turn it into a feature layer. This arcpy code should help: import arcpy FC = r"C:\...\featureclass" arcpy.MakeFeatureLayer_management(FC, "nameoffeatureclass") MXD = arcpy.mapping.MapDocument(r"C:\...\your.mxd") DF = arcpy.mapping.ListDataFrames(MXD) layer = ...
GPX File Support has 820 points so far on the ArcGIS Ideas page, so I guess there are few people around waiting for this functionality (vote on the Ideas page please! :]). There are few ways to tackle this problem (in no particular order): Use GPSBabel to convert your GPX files to CSV and then import them into Arc. Use GPX to Features Tool from script ...
Because this is a local operation, let's work out how to do it for a single cell: Map Algebra will take care of the rest. First note that the order of the rasters obviously matters. Therefore single-shot cell statistics, such as a cell sum, won't do it. If we were to encounter a sequence such as 01110101 at a given cell, we would process this from start ...
Reverse Geocode Tool Documentation. Your data needs to be in a format that ArcGIS will recognize as a layer (shapefile, geodatabase feature class, etc.). If you just have XY's in a table, consider adding your table to ArcMap then using the add XY data tool to create a layer you can use in the reverse geocode tool.
The workaround is to click on the Count heading, which will force ArcMap to count the features. As an aside, this can be the fastest way to view the frequency distribution of your data. Rather than using the > Table > Summarize option, just create a Unique Values symbology using the field you're interested in, view the Count, then hit Cancel so you don't ...
