Server Object Interceptor (SOI) to Visualize Features with On The Fly Aggregated Values from Time-Series or Historical Observation Data

aggregated layer no UI

A sample SOI (Server Object Interceptor) is made available that helps visualize on the fly aggregated results by overcoming challenges presented in an earlier blog post. A map service, powered by this SOI, can be used in the ArcGIS Online Map Viewer … Continue reading

An alternative to overlaying layer tints on hillshades

By Rajinder Nagi, Esri Cartographic Product Engineer

Overlaying rasters - thumbnail

A common cartographic technique is to transparently overlay a colored raster, called a layer tint, over a grayscale raster, like a hillshade or a panchromatic aerial or satellite image. When you display a colored raster transparently over a grayscale raster, you lose the intensity of your colors and that it is harder to see the hillshade details. Continue reading

Changes to ArcGIS Desktop basemaps

The National Geographic basemap has now been added to the File > Add Data > Add Basemap dialog in ArcGIS Desktop 10. It has also been added into the list of basemaps that appears if you choose the File > Add Data From ArcGIS Online command in ArcGIS Desktop 9.3.1.

 

In the Add Basemap dialog, the Shaded Relief basemap entry has been removed in order to make space for the National Geographic basemap and keep the number of basemaps to 12. However, we have updated the Terrain basemap so that it includes the Shaded Relief service. So if you want to add shaded relief to your map, choose the Terrain basemap, and then in the Table Of Contents you can choose between the terrain service and the shaded relief service, whichever looks best for your map. The layer also includes reference overlays that you can turn on.

Managing layer visibility and selections

Managing layer visibility and selections with the table of contents’ List By Visibility mode

The table of contents in ArcGIS 10 has several ways of listing the layers in the map: by drawing order, source location of the data, whether layers are visible, and whether layers are selectable. A particular list type may be more useful than others depending on the current mapping task. For example, List By Drawing Order is best at setting which layers draw on top of others and List By Source works well to help repair broken data links for layers from different workspaces. In an earlier post, I focused on the table of contents’ List By Selectable mode when I wrote about refining the selected features while editing. In this post, I am going to show how I can use List By Visibility to manage layer visibility and selections.

New ArcGIS Online Basemaps

A couple of nice additions to the ArcGIS for Desktop 10  basemap gallery were made last week:

1. We added an entry for the new Light Gray Canvas basemap which provides a neutral basemap that makes your thematic data really stand out. There are some useful blog posts about this new basemap on the Mapping Center blog

2. We renamed the  ‘Physical’ basemap to ‘Physical and Ocean’ and added the Ocean basemap
into this as a layer. When you add the Physical and Ocean basemap into
your map, you can turn the Ocean basemap on in the entry for this
basemap in the Table Of Contents if you want to see rich detail for the
world’s oceans.

To add  these basemaps into ArcGIS for Desktop 10, choose File > Add
Data > Add Basemap in ArcMap or ArcGlobe. To add them into 9.3 or
9.3.1, choose File > Add Data From ArcGIS Online.
Alternatively, here are the layer packages for the Light Gray Canvas basemap and the Physical and Ocean basemap that you can add directly into your map or globe.

To add these basemaps into your map or globe via the Catalog, make a connection to this ArcGIS server: http://services.arcgisonline.com/arcgis/services
and then add the World_Light_Gray_Base and World_Light_Gray_Reference
services from the Canvas folder, or the Ocean_Basemap service.

ArcGIS 9.3.1 Desktop Layer Packaging Patch

Now that everyone has downloaded and installed ArcGIS 10 and applied Service Pack 1, here is an important patch if you are sharing your layer packages with ArcGIS 9.3.1 users.

This patch addresses
an issue that prevented users from being able to unpack/open ArcGIS 10
SP1 layer packages (*.lpk files) in ArcGIS 9.3.1. This patch is required for 9.3.1 ArcGIS users who want to consume layer packages created in ArcGIS 10 SP1 Desktop.

Creating Place Name Indexes for Map Books

ArcGIS 10 includes the ability to make multiple-page map books using data driven pages. However, map books are often a collection of information in addition to the maps, for example, title pages, tables of contents, and index pages.  So, in addition to data driven pages, ArcGIS 10 includes the arcpy.mapping Python module that provides the ability to create and combine a series of pages into a final map book product.  

Building an index or gazetteer of place names is a common requirement for map books, and data driven pages by themselves do not provide a solution for building the index pages. However, Python scripting can be used to create these. We have placed a sample on the Resource Center to help. The sample combines the use of Data Driven Pages, arcpy.mapping, and a 3rd party PDF design toolkit called ReportLab to create a final map book product with index pages.

 

Indexes can vary greatly from organization to organization. The rules for what is indexed, how the index table is compiled, and the index formats can differ widely.  This sample provides one example. However, both the geoprocessing workflow and script can be customized for your particular index needs (Note:  In the geoprocessing steps in this example the Frequency tool is used that requires an ArcInfo license.).  Also, one of the nice things about using ReportLab is it gives you all sorts of formatting options for the results.  The arcpy.mapping Map Book with Index Pages sample can be downloaded here.

Converting KML to Layer Packages

ArcGIS Explorer desktop can view KML in both 2D and 3D. ArcGIS Desktop
(ArcMap) can export KML, but does not yet enable you to view it. So how do you
view your favorite KML in ArcMap? One way is to use a new capability of the
latest ArcGIS Explorer release and convert it to a layer package. For more information see this post from the Explorer blog.
