or 10.2 product. The settings for the installation location, license manager (for Concurrent Use), or authorization information (for Single Use or ArcGIS Server products) are retained in the upgrade. See the following reference guides for more information on installation upgrades, new installations, or installations over versions previous to 10.2.

The ArcGIS 10.2.1 release includes stability enhancements and improved functionality for the following ArcGIS products: ArcGIS for Desktop, ArcGIS for Server, ArcGIS Engine, Business Analyst Desktop, Portal for ArcGIS, and ArcGIS for Desktop and Server Extensions (Aviation, Maritime, Data Reviewer, Workflow Manager, Roads and Highways, and GeoEvent Processor).

Correction: This post incorrectly listed "Location Analytics (Business Analyst (BA) Desktop, BA Server)" as part of the stability enhancements and functionality improvements included with the 10.2.1 release. This has been corrected to state, "Business Analyst Desktop". -->
SSB: Describe a day in the life of a group lead.Prasad: As a group lead I have multiple roles. I look into resources within the team and I make sure that all the operation tasks are executed efficiently on a daily basis. I also have to meet the operation KPIs and ensure that there is no breakdown in the support process.SSB: What kind of support incidents do you face daily?Prasad: Currently we support product licensing issues. We also assist customers with installing their various Esri products. At the moment we are only handling licensing and implementation issues, but moving forward as the team matures, we will be opened to various kinds of technology to provide overall support for customers.SSB: What are the pros and cons of leading a team?Prasad: I would say people management is a con, but it is a challenge I've taken on as a lead. The pros of leading a team are that it gives you the room to push your capabilities in producing results, and the role teaches you a valuable lesson in what it takes to manage a team successfully.SSB: You've recently been commended for doing a great job in leading your team - what would you say has been your biggest inspiration and motivation?Prasad: Self-confidence! That's what drives and motivates me. Also, based on experience and the nature of the industry I've been exposed to, I like to be challenged. My inspiration is - be the best in what you do.SSB: What are your hobbies and interests?Prasad: My hobbies and interests have always been sports, especially football, and travelling. I've played football for the state and for a local club. And I travel for football matches too! I've been to Old Trafford in the UK a couple of times for football matches and my ultimate goal is to attend a World Cup football match - football is my most passionate hobby. Apart from travelling for football, I also love travelling to explore other countries and their culture. I've already covered South East Asia; I've been to parts of Europe, the Oceanic countries and South America. I've yet to visit the Middle East and Africa and I'm keen to.SSB: Do you have any tips or useful suggestions for other aspiring team leads?Prasad: Ensure quality in work and strive for excellence and efficiency. If someone is aspiring to be a team lead, emphasis on team work is very important as no success can be achieved individually. I'm a firm believer in working closely with my team. And above all, be patient and do not be rash when you make decisions.Rajeshwary K. - Online Support Resources

The Define Projection tool

Spatial data implicitly has coordinate values in either geographic or projected coordinates. A geographic coordinate system (GCS) uses a three-dimensional spherical surface to define locations on the earth; whereas, a projected coordinate system is defined on a flat, two-dimensional surface. Unlike a geographic coordinate system, a projected coordinate system has constant lengths, angles, and areas across the two dimensions. However, we need to explicitly define the coordinate system of our data. If  we have undefined data, then we can use the Define Projection tool to define it. Otherwise, when data without a defined spatial reference is added to ArcMap, a dialog box will display that lists the data sources that are missing spatial reference information.


Figure 1: Dataset missing Spatial Reference

If the data that you added to ArcMap has coordinate values that are projected, 'Unknown Units' will be displayed next to your coordinates in the data view until the projected coordinate system is defined.


Figure 2: The units are listed as Unknown

If the dataset that you added to ArcMap has geographic coordinates, the units will still display as ‘Decimal Degrees’ or in Degrees, Minutes and Seconds (DMS) (e.g. 82°45'46.8"E 41°44'56.4"N) even though the datum has yet to be defined. This is because latitude and longitude values always have angular units.

Figure 3: The Decimal Degrees units are displayed even though it's undefined

Defining a geographic or projected coordinate system for a shapefile, Esri Grid format, raster dataset (TIFF, JPG) or a file geodatabase does not require you to output to a new dataset. The Define Projection tool updates your existing dataset by creating an associated file (e.g. .prj, prj.adf,.aux). For personal geodatabases, the spatial reference table is updated.

For shapefiles, Esri Grids, raster datasets, and file/personal geodatabase feature classes you will need to go to ArcToolbox > Data Management Tools > Projections and Transformations > Define Projection to assign a geographic or projected coordinate system to your dataset.

A principle of good data management is to obtain the projected or geographic coordinate system parameters from your data source provider or associated metadata. It is strongly advised that you do not make an educated guess about the coordinate system of your data, as an inaccurate GIS database usually results. However, if you do not have access to the data source provider you can try using the steps in Esri Knowledge Base Article 24893 to identify an unknown projected coordinate system using ArcMap.

 The Project tool

To change from one coordinate system to another, use the Project tool from ArcToolbox. When using the Project tool a new output dataset is created.

For shapefiles and feature classes, you will need to go to ArcToolbox > Data Management Tools > Projections and Transformations > Feature > Project to transform your dataset to another coordinate system.


Figure 4: The Project tool

 To project multiple shapefiles or feature classes:

  1. Right-click the Project tool and select the Batch mode.
  2. Select the shapefile or feature class to be projected.
  3. Specify a location and name for the new projected data.
  4. If you're using the Batch mode of the Project tool, double-click the output dataset cell to browse to a location and save.

After specifying the location and name for the new projected data, specify the output coordinate system to project the data. If it is required, select an optional geographic transformation and complete the projection!
