LOADING MICROSOFT BING IMAGERY AND ROAD NETWORK INTO ARCGIS 10



This tutorial will explain how to load Microsoft online Bing imagery and Road Network into ArcGIS 10.
ESRI manages a series of ready-to-use basemap layers that you can add directly to your map for free.
They are called ArcGIS Online basemaps and they’ve been available since version 9.3.1.  At version 10, however, you can access them directly with no need to register or download links.
The basemaps include aerial imagery used by Bing Maps, Street Map data, USGS topo maps, relief maps, and more.
Instead of having your data floating on white background, you can add basemap layers and create the professional and interesting maps with saving lot of time
With version 10 you can directly add basemap without registering or any alternates download links.
1)    Start ArcGIS,
2)    Go to File menu bar, select Add Data, Select Add Basemap.


3)    Or directly from Add Data Button which include a dropdown menu with the option to Add Basemap

 
4)    Add Basemap window will show the Basemaps types.
 

5)    Out of that we will choose Bing Imagery.
6)    It will be added in TOC (Table of content) as like the layers

 

7)    The map of the world appears with Bing data loaded, you can pan, zoom this database
8)    Now you can use these for plotting, adding geo-referencing features, for adjusting scanned maps, and many other numerous productions.

Learn How to Create a Map Topology in ArcGIS 10.1




When editing map data, you often have features that share boundaries. For example, you may have a forest border that meets the edge of a stream or a lake polygon that shares borders with land-cover polygons and shoreline features. Editing with topology can reduce the chance of introducing inadvertent gaps or overlaps between features that share geometry. You can create a simple map topology to make updates simultaneously to all features that are coincident.

Aligning features and editing coincident geometry through topology has been made easier with ArcGIS 10.1. The new Select Topology dialog box consolidates into one step the process of creating and activating a map topology, which is available for all license levels of ArcGIS for Desktop.
To create a map topology in ArcMap, first add all the layers you want to edit together to your map. You can edit geodatabase feature classes or shapefiles with a map topology.
Step one: Click Customize, point to Toolbars, and add the Editor and Topology toolbars to ArcMap. The Topology toolbar has been redesigned in ArcGIS 10.1 so that it contains only commands that are directly related to topology. All other commands previously on this toolbar, such as Construct Polygons, have been moved to the Advanced Editing toolbar.

The Topology toolbar




Step two: On the Editor toolbar, click the Editor menu and click Start Editing to begin an edit session.

The Editor toolbar




Step three: On the Topology toolbar, click Select Topology. This opens the Select Topology dialog box.

On the Topology toolbar, click Select Topology.




Step four: Check the layers that should be edited together. In ArcGIS 10.1, map topology uses layer information and reflects layer properties, including name and visibility, rather than the properties of the underlying feature class as it did in previous releases. Annotation, dimension, or feature classes that participate in a geometric network cannot be included in a map topology.

Step 4

Step five: Optionally, click Options to view the cluster tolerance, which is the distance that defines how close together edges and vertices must be to be considered coincident. Because ArcMap automatically determines the minimum possible cluster tolerance, you should generally use the default, because increasing the value can cause features to collapse or distort. To get information about what you can do with topology, click the About editing topology link. This opens the related topic in the help system.

Step six: Click OK.
That's all you need to do to set up a map to edit coincident features. If you happened to click a topology editing tool without already having a topology set up, you would be prompted to create a map topology using this dialog box.
Now that you have an active topology, edit with the tools on the Topology toolbar to make sure your features remain coincident. Use the Topology Edit tool to select edges so that you can move, modify, and reshape them. If you want to select multiple edges that form a path so you can reshape them all at the same time, you can either use the new Topology Edit Trace tool or simply hold down the left mouse button using the Topology Edit tool.
To learn more about enhancements to editing features with topology, see the Editing topology and New tools for aligning data sections in "What's new for editing in ArcGIS 10.1."

DEM Surface Tools for ArcGIS



Description:  This extension provides you with tools to generate a variety of surface characteristics of a landscape, using both projected and unprojected (i.e. latitude / longitude) digital elevation model (DEM) rasters. These tools include:
  1. Surface Area and Ratio of a landscape
  2. Slope, with 3 slope algorithm options
  3. Aspect, with 3 aspect algorithm options, and an additional tool to apply a traditional directional Aspect symbology to an existing Aspect raster.
  4. Hillshade, with optional hypsometric tinting
  5. Multi-directional Oblique-Weighted Hillshade, with optional hypsometric tinting
  6. Seven types of Landscape Curvature

ArcGIS has many useful tools for calculating slope, aspect, hillshade and curvature from DEM rasters. This extension offers some advantages over these existing tools in that:

  • These tools correctly handle Latitude / Longitude Data: The existing ArcGIS tools typically do not work well with data in a geographic coordinate system (i.e. Latitude / Longitude coordinates). They expect the vertical units of a digital elevation model to be the same as the horizontal units, and at best they only allow you to enter in an adjustment factor (generally called a "Z-factor") to adjust your Z-units to your X/Y-units. This Z-factor adjustment method is cumbersome to implement with latitude/longitude coordinate systems because the correct Z-factor is both hard to calculate and changes with latitude. Geographic data is especially confounding because the X-units are not the same as the Y-units. Both are in "degrees", but a degree in latitude (Y-units) is not the same distance as a degree in longitude (X-units).                                                                         Unfortunately, most free elevation data available online is only available in latitude/longitude coordinates. This data can be projected, but projecting raster data introduces errors in resolution and precision (see horizontal and vertical artifacts on illustration in manual). This extension modifies the algorithms used to calculate common morphological characteristics of the landscape so that they accurately work with latitude/longitude data without projecting the data or using Z-factor adjustments. All methods are described in detail in the manual, but in general this extension will always automatically detect the coordinate system of the raster and use the method appropriate for that coordinate system

  • These tools offer several options not available in the standard ArcGIS toolsIncluding multiple slope and aspect algorithms, optional hypsometric shading for hillshades, the MDOW model for hillshades, and many more options for landscape curvature. 
  • Surface Area and Ratio: This extension allows you to generate Surface Area and Surface Ratio rasters from an existing Elevation raster. The cell values for these new rasters reflect the surface area and (surface area) / (planimetric area) ratio for the land area contained within that cell's boundaries. Both Surface Area and Surface Ratio provide useful indices of topographic roughness and convolutedness, and can give a more realistic estimate of the land area available than you can get from the simple planimetric area. 

  • These tools do not require Spatial Analyst: This extension uses only standard ArcGIS ArcObjects functions and therefore does not require a license for either Spatial Analyst or 3D Analyst.


Requires:  ArcGIS 9.2 or better, at any license level, or ArcGIS 10.

Important:  This extension does not require Spatial Analyst or 3D Analyst.  It will work just fine without any add-on extensions

Tools for Comparing and Analyzing Geodatabase Schemas

I found a very intersting  suite of tools written in Python for analyzing components of a geodatabase and for finding the differences between geodatabase schemas and thanks to Brooke Reams , Geospatial Analyst at Esri, for this suite. 
 The tools are accessible through an ArcGIS Toolbox called SchemaInspector.tbx. They are grouped into three categories:
1. Analyzer Tools
2. Diff & Compare Tools
3. Diff Tools

There are five tools under the Analyzer Tools toolset. These tools are for printing properties of a single geodatabase component. Each tool has parameters for the input workspace and the output text file (the output text file does not have to pre-exist).
1. Analyze Domains
- Prints properties to a text file for each domain in a workspace including Domain Type, Range, Field Type, Merge Policy, and Split Policy.

2. Analyze Feature Classes
 - Prints properties to a text file for each feature class in a workspace (geodatabase or feature dataset) including Shape Type, Shape Field Name, Feature Type, Spatial Index, Has M, and Has Z.

3. Analyze Fields
- Prints properties to a text file for each selected field in a feature class including Type, Alias, Base Name, Domain, Editable, Nullable, Length, Precision, Required, and Scale.

4. Analyze Relationship Classes
- Prints properties to a text file for each relationship class in a workspace including Backward Path Label, Cardinality, Class Key, Destination Class Names, Forward Path Label, Attachment Relationship, Attributed, Composite, Reflexive, Key Type, Notification, and Origin Class Names.

5. Analyze Tables
- Prints properties to a text file for each table in a workspace including Has OID and OID Field Name.


There are six tools under the Diff & Compare Tools toolset. These tools are for comparing particular geodatabase components between two workspaces. Each tool has parameters for the two schemas to compare and the output text file.
 1. Domain Diff & Compare
- Prints the names of domains that are not common between workspaces to a text file. Searches common domains and prints domain names and properties (same properties as the Analyze Domains tool) for domains with the same name but with different properties.

2. Feature Class Diff & Compare
- Prints the names of feature classes that are not common between workspaces to a text file. Searches both standalone feature classes and feature classes in feature datasets. Searches common feature classes and prints feature class names and properties (same properties as the Analyze Feature Classes tool) for feature classes with the same name but with different properties.

3. Field Diff & Compare (by Feature Class)
- Prints the names of fields that are not common between feature classes to a text file. Searches common fields and prints field names and properties (same properties as the Analyze Fields tool) for fields with the same name but with different properties.

4. Field Diff & Compare (by Workspace)
- Prints the names of fields that are not common between all feature classes in the workspaces to a text file. Searches both standalone feature classes and feature classes in feature datasets. Searches common fields and prints field anmes and properties (same properties as the Analyze Fields tool) for fields with the same name but with different properties.

5. Relationship Class Diff & Compare
- Prints the names of relationship classes that are not common between workspaces to a text file. Searches common relationship classes and prints relationship class names and properties (same properties as the Analyze Relationship Classes tool) for relationship classes with the same name but with different properties.

6. Table Diff & Compare
- Prints the names of tables that are not common between workspaces to a text file. Searches common tables and prints table names and properties (same properties as the Analyze Tables tool) for tables with the same name but with different properties.


There is one tool under the Diff Tools toolset. This tool is called Workspace Diff and combines all of the tools under Diff & Compare toolset into a single tool. There are parameters for the two schemas to compare and the output text file.


All of the tools can be used with Basic, Standard, and Advanced license levels. The tools can be used with ArcGIS 10.0 or higher, with the exception of the Analyze Domains tool, the Domain Diff & Compare tool, and the Workspace Diff tool which require ArcGIS 10.1 or higher (to use the Workspace Diff tool on 10.0, simply comment out the lines that compare domains [361 - 387] in the ws_diff.py file).

The SchemaInspector.tbx and all of the tools described above can be downloaded from the Geospatial Database for free. Right click on the link below and select Save As... to download the zip containing the .tbx and .py files. Unzip all of the files to the same folder location (toolbox and scripts use relatives paths). The tools can be accessed and executed from both ArcMap and ArcCatalog.
