GEMS: (Gas and Electric Mapping System) is an automation application for Autodesk MAP and Raster Design that allows a Mapper to Check out a Hybrid Grid Map through an Oracle database, Load Adjacent maps, Save Project maps, Check in or Cancel Checkout of the maps, and Place Commodities and Facilities on the maps.

This is an extensive application with over five years of specifications and coding. Below you will find an overview of the Document Management portion. There are also automations for inserting Commodities and Facilities that will not be overviewed here to preserve the confidentiality of the client.

Key Benefits:

The Login command allows the Current User to log in to Oracle. The User field is read directly from the Autodesk MAP session. When the Current User enters a Valid Password, it is encrypted and stored in the registry. All GEMS commands look for the encrypted registry entry. If it doesn't exist, they are funneled through the Login code stream to validate the Current User. If the Current User cancels the login, the GEMS command issuance is terminated.

The Create New command is the basis for new Maps to be generated, and subsequently placed in the Active Grid in True World Space. The dialog box entries are the required entries to populate the Oracle database. Extensive Database Validation prevents a map of the same Office, Drawing Name, Drawing Type, and Scale from being generated. All new maps are at Status level Inactive | New.

The Register command allows the Current User to Register a Map into the Oracle database, and move the Source Files used to create the Map up to the File Server. The dialog is automatically populated with the data entered during the Create New command with the exception of either the Lower Left coordinate or the Upper Right coordinate, which are variable based on the scale of the Map. All Maps are Created and Registered with a Status Level of Inactive | New. The Map must be Checked out, and Checked back into the system with a Status Change to be placed in the Active Grid.

The Check out command allows the Current User to Check out a Map of a current Office and Drawing Type by Drawing Name or by Coordinates. The Browse button will pull a record set from Oracle for the selected Office and Drawing Type. The Browse button is only active during a Check out by Drawing Name. During a Check out by Coordinates, if two or more scales of Maps are found on the entered coordinates, the Current User is presented with a list of scales found, and must select a scale to filter the session. All Load Adjacent commands are locked in to Office, Drawing Type, Scale, and Map Status level to ensure the proper commodity is loaded.

The Check in and Cancel Checkout commands allow the Current User to finalize or throw away Map edits respectively. During a Check in the Current User can also change the Status Level of a Map rendering it a part of the Active Grid, or taking it off line as Inactive.

The Open Project command allows the Current User to open an existing project that has been closed to the harddrive... and yes, we did figure out a way to save an Autodesk MAP query session and re-open it without disassociating the queried entities!
