Welcome to the new unified ArcGIS Blog

For the past few years the various ArcGIS product development teams have hosted a few dozen separate blogs covering the width of the ArcGIS system. Now we have pulled those together into a single ArcGIS Blog so that you can more easily browse, subscribe to, learn from, and stay up-to-speed on the latest information from all our engineers and developers. In addition, the single blog reflects ArcGIS as a system and allows us to better tell big picture implementation stories that we couldn’t in the fragmented system.

If you do want to narrow your focus, just click a Category (under Technical Communities and Industry Communities) or Tag to see the posts for that particular area. You should find a category or tag that matches up with the subject area for each of the old separate blogs. A few may have been overlooked or thought to be unnecessary. We appreciate your feedback on specific categories or tags that should be added to help focus in on subject matter that is of interest to you. Continue reading

National Geographic World Basemap

National Geographic and Esri have collaborated to produce this cartographically distinctive basemap that reflects National Geographic’s cartographic design, typographic style, and map policies.

This basemap provides a visually appealing background for web mapping applications for mobile users, consumers, and educational purposes, and is also well suited as a general reference map for many GIS projects.

This National Geographic World Map has been added to the collection of existing ArcGIS Online basemaps that users can access freely for internal and external use.

Get more details about this map and start using it today.

Alley Vacation part 1

The parcel fabric data model lends itself to many improved workflows for managing your parcels, particularly when it is used in conjunction with the Local Government Data Model and Tax Parcel Editing Template for ArcGIS 10, which you can download from the resource center.  Some of these improved workflows are hard to detail in the help, though, so we’re hoping some blogs will help out.  One of these workflows comes from the City and County of Denver and centers on how you perform a vacation of an alley or right-of-way parcel.  The City and County are using the Local Government Data Model, which provides the ability for managing not only parcels, but also Lots and Subdivisions.

There are a few things to consider before performing an
alley vacation or creating any new parcel(s). 

1. Does the alley exist in the lot layer?

If the alley exists, the first step
before doing any work would be to make sure the original lot (alley) is marked appropriately
in the historic layer (marked as Vacation).

2. How accurate are the measurements on the
adjacent block edges/lots?

In the data that was used for this
example, the lots should be 125 feet by 25 feet, but a look in the parcel
description shows the measurements are off for some of the lots.



The best practice in this case is to
re-enter the original blocks by cogo-ing the outer boundary of the block from
recording, and then using the Parcel Division tool or Construction to recreate
the lots. Once completed, these blocks can be joined to the Fabric using
control points or even orthophotography. 
Of course, the tax parcels would also have to either recreated from the
lots or re-joined to fit the newly constructed lots.

The first workflow listed below can be used
for this task.  In a later post, will
talk about how to complete this process without recreating the lots.

Recreating Blocks and Lots from Records (original city subs)

1. Mark original lots historic or delete them all
together from the Fabric.  In this example,
I’ve left this step until the end so that I can use the lots as reference to
name the new ones

2. COGO entire block boundary from record.  For this example, all of the lots are 125 X

a. Create a new Plan, and give it an appropriate

b. Create a new construction inside that plan, set
the parcel template to “lots”


 c. COGO the outer boundary like this:


Please note that the alley was divided two pieces.  More on that later.  Also note that the original lots are displayed in the background.

d. Delete the 575’ measurement


 e. Select the Segmented Line Tool from the top of the Parcel Details window:


To start, make sure you cursor is in the FROM cell of the next available row and click in the grid to replace the NW corner, type “23” to get 23 equal segments or right click.

f.   Click the SW corner, and do the same thing for all the other edges.

     <img src="http://downloads.esri.com/blogs/arcgisdesktop/alley7.jpg"


g.  Digitize in the connect lot lines, create a connection line for the center of the Alley.


3.  Build and Join.  For this example, the parcels are turned off and we joined directly to photography as control.  Later on, the data can be re-adjusted to proper control if desired.

<img src="http://downloads.esri.com/blogs/arcgisdesktop/alley9.jpg"

a. Then create any join links between the existing Parcels and the new lots…make sure to have points turned on for this!


b. Hit OK, and the data will now look like this:



4. This will make the ROW (Alley) Vacation easier since you now have the centerline of the ROW (Alley) to use to expand the tax parcels.

 a. With the Tax Parcels and just the ROW (Alley) in question selected, we can use the Construct From Parent option to do the rest of the line work.



b.  We can digitize over the connection lines, creating new lines that extend the current tax parcels.  The Planarize command can be used to get rid of any excess.  We then build to create polygons and merge the smaller vacation leftovers to the current tax parcels, carrying their attributes over to the newly expanded parcel.



c.  Finally, mark ROW (Alley) Vacated (Historic).

Advanced labeling for the stretch renderer


Do you like the visualization of the stretched renderer, but wish you could label more than three values? The Labeling button on the stretched renderer allows you to create breakpoints, choose a color for each breakpoint, and chooe a label for each breakpoint. It is like a hybrid between the stretched renderer and classified renderer. Continue reading
