Oracle Spatial Extension in AutoCAD Map 3D dead and gone

The Oracle Spatial Extension was a tool that enabled AutoCAD Map 3D to push your DWG directly in Oracle.  Your Block Definitions, Block Attributes, Object Data and Link Templates were all maintained in Oracle and you could round trip back and forth from Oracle to DWG and back again with a READ/WRITE button.

MAPOSEREAD

This extension was added in AutoCAD Map 2000- but only for 32bit.
Those days are past, although if you install 32bit version of AutoCAD Map 3D 2015 you might still get it to run.

Yet I doubt you’ve been able to buy a 32bit computer in any store in the past 5 years.

I talk about it in detail in my AUGI post here:   https://www.augi.com/library/highs-and-lows-of-moving-dwg-into-a-database

Luckily there is FDO (Feature Data Objects).  This is a generic data connection tool found in products such as AutoCAD Map 3D, InfraWorks, AutoCAD Civil 3D, Autodesk Infrastructure Map Server AND MapGuide.

You can connect to more than just Oracle such as SDF, SHP, SQL Server Spatial, ArcSDE, and almost anything that Safe Software’s FME can connect to with the FDO Provider for FME (http://www.safe.com/solutions/for-applications/autodesk/autodesk-autocad-map-3d/fme-fdo-provider/)

Now there are a few organizations out there that still store their data in OSE (ask them and they don’t want to move since the DWG round tripping to Oracle and back is so seamless).  But, now we are in the 64bit world, we may have to move forward.

In this document that I wrote for Autodesk a number of years ago, I talk about moving from Oracle OSE to FDO using AutoCAD Map 3D.  The information is still relevant for all those OSE users:

Moving from OSE to FDO with AutoCAD Map 3D

Although the document moves OSE data to Oracle, there is no reason you can’t move OSE data from Oracle to any FDO data source.  I have recently used this technique to move OSE data in Oracle to SQL Server Spatial 2012.

Pre-work for Autodesk University 2014 – Life of a Building Footprint

After arriving in Las Vegas today for the beginning of Autodesk University 2014, I have been reviewing my presentation.
https://events.au.autodesk.com/connect/sessionDetail.ww?SESSION_ID=5030

This class touches on the following products:

  1. AutoCAD Map 3D
  2. Autodesk Raster Design
  3. Autodesk InfraWorks 360
  4. SketchUp
  5. Autodesk Infrastructure Map Server
  6. MapGuide Maestro
  7. Google Earth
  8. mapguide-rest project
  9. Cesium

All this in 90 minutes.

It’s a lot to cover, but it is some of the tools we need to publish data to the web.

There should be a lot more GIS-y things at AU, but AutoCAD Map 3D and Infrastructure Map Server have not had many big functionality increases over the past few years, so they don’t get much press.  They still are used by thousands of users everyday, but the tools you use every day are not considered “sexy”.

Hopefully there will be some big leaps in the products soon  –  like integration with Cesium – or seamless round tripping from DWG to FDO and back (using block rotations, object data, etc) – this was done extremely well with an old Oracle Spatial Extension but doesn’t work with 64bit now.

Fingers crossed.

Autodesk MapGuide 6.5 Retired But Still Downloadable

Here are the links to download MapGuide 6.5 Service Pack 1 (for now):

MapGuide ActiveX Control

MapGuide Author 6.5

MapGuide Server 6.5

MapGuide SDF Loader 6.5

MapGuide Raster Workshop 6.5

MapGuide Dynamic Authoring Toolkit 6.5

MapGuide Component Toolkit 6.5

 

Use at own risk as these products are no longer supported!  I have been continuing to consult with people to help move them to Autodesk Infrastructure Map Server 2014 or MapGuide Open Source – let me know if you need help migrating.

Autodesk Infrastructure Map Server – Auto-Zoom On Load

Whether you are using AIMS 2014 or MapGuide OpenSource 2.5, there is a way to automatically zoom and highlight objects.

I will do this demo using FUSION or Flexible Web Layouts.

We want to be able to pass parameters to the template like the following.

http://localhost/mapserver2014/fusion/templates/mapguide/slate/index.html?LAYERNAME=Roads&KEYNAME=ID&KEY=644,684&ISSTRING=1

The parameters are:

  • LAYERNAME
  • KEYNAME
  • KEY
  • ISSTRING

The LAYERNAME is the layer name in the map (i.e. Roads)
The KEYNAME is the column you want to search by (i.e. ID)
The KEY is the comma delimited list of matches (i.e. 644,684)
The ISSTRING flag tells whether the KEYNAME is String or Number.

I am using the SLATE template in MapGuide/AIMS, found in C:\Program Files\Autodesk\Autodesk Infrastructure Web Server Extension 2014\www\fusion\templates\mapguide\slate\index.html

To start the process, we need to trigger a javascript function once the map is loaded, around line 174, add a call to a function called zoomToObject()

var initPanelHandler = function() {
zoomToObject();
if(isTaskPaneRegistered) return;

Next create a zoomToObject() function that will pass all the parameters to a PHP Page to get the selectionXML, (paste this above the var showOverviewMap = function() { line):

function zoomToObject()
{
var mapWidget = Fusion.getMapById('Map');
var SESSION =mapWidget.aMaps[0].getSessionID();
var MAPNAME = mapWidget.aMaps[0].getMapName();

var KEY=getParam('KEY');
var ISSTRING=getParam('ISSTRING');
var KEYNAME=getParam('KEYNAME');
var LAYERNAME=getParam('LAYERNAME');

//The GETSELECTIONXML.php returns the XML of selected features.
var AJAXURL = "/mapserver2014/GETSELECTIONXML.php?MAPNAME=" + MAPNAME;
AJAXURL = AJAXURL + "&SESSION=" + SESSION;
AJAXURL = AJAXURL + "&KEYNAME=" + KEYNAME;
AJAXURL = AJAXURL + "&LAYERNAME=" + LAYERNAME;
AJAXURL = AJAXURL + "&KEY=" + KEY;
AJAXURL = AJAXURL + "&ISSTRING=" + ISSTRING;

var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
mapWidget.setSelection(xmlhttp.responseText, true);
}
}
xmlhttp.open("GET",AJAXURL,true);
xmlhttp.send();

}

we also need the getParam() function to harvest the parameters sent to the page:


function getParam(sname)
{
var params = location.search.substr(location.search.indexOf("?")+1);
var sval = "";
params = params.split("&");
// split param and value into individual pieces
for (var i=0; i<params.length; i++)
{
temp = params[i].split("=");
if ( [temp[0]] == sname ) { sval = temp[1]; }
}
return sval;
}

Finally, the GETSELECTIONXML.php (I put this in the www folder of C:\Program Files\Autodesk\Autodesk Infrastructure Web Server Extension 2014\www\)

<?php

$configFilePath = "C:\Program Files\Autodesk\Autodesk Infrastructure Web Server Extension 2014\www\webconfig.ini";

$session = urldecode($_REQUEST["SESSION"]);
$mapName = urldecode($_REQUEST["MAPNAME"]);

$keyName = urldecode(stripslashes($_REQUEST["KEYNAME"]));
$layerName = urldecode(stripslashes($_REQUEST["LAYERNAME"]));
$isString = urldecode(stripslashes($_REQUEST["ISSTRING"]));

$key = urldecode(stripslashes($_REQUEST["KEY"]));

if($isString == true)
{
$key = $key . ',0';
$key = str_replace(",", "','", $key);
$key = "'" . $key . "'";
}

try

{
MgInitializeWebTier($configFilePath);

$userInfo = new MgUserInformation($session);

$siteConnection = new MgSiteConnection();

$siteConnection->Open($userInfo);

$featureService = $siteConnection->CreateService(2);

$resourceService = $siteConnection->CreateService(0);

$map = new MgMap($siteConnection);

$map->Open($mapName);

$queryOptions = new MgFeatureQueryOptions();

$queryOptions->SetFilter($keyName . " in (" . $key . ")");

$layer = $map->GetLayers()->GetItem($layerName);

$parcelDataResId = new MgResourceIdentifier($layer->GetFeatureSourceId());
$featureClassName = $layer->GetFeatureClassName();

$featureReader = $featureService->SelectFeatures($parcelDataResId, $featureClassName, $queryOptions);

$selection = new MgSelection($map);

$selection->AddFeatures($layer, $featureReader, 0);

$selectionXml = $selection->ToXml();

$selection->Save($resourceService, $map->GetName());

//dump the XML out to a JAVASCRIPT variable

echo $selectionXml;

}

catch (MgException $e)
{

echo $e->GetMessage();

echo $e->GetDetails();

}

?>


That’s it.  It will work with the sample data that comes with MapGuide and AIMS, Sheboygan, or with any map you wish.

This will work with any FUSION application (flexible web layout),  on any version of mapguide.  The only thing you have to change is this line:

$configFilePath = “C:\Program Files\Autodesk\Autodesk Infrastructure Web Server Extension 2014\www\webconfig.ini”;

Just point it to the correct www folder.

Canadian cities ‘hopeful’ about fed. budget pledge for infrastructure

Article from Sat. March 16, 2013 Globe and Mail news section. I’m optimistic the fed’s acknowledgement of underfunding for municipalities will trigger a wave of investment for our crumbling cities.

http://www.theglobeandmail.com/news/politics/canadian-cities-hopeful-about-federal-budgets-new-pledges-for-infrastructure/article9842096/

The first thing that municipalities must do is create a detailed inventory of their infrastructure assets (pipes, hydrants, etc).  This is done with a combination of CAD and Geographic Information Systems.

Creating an inventory is just the first step not a complete system.  Municipalities also need the purchasing, work order and maintenance components to manage their infrastructure.

Systems such as Maintenance Connection, provide GIS/CAD inventory in conjunction with the entire asset management system.

Arrow Geomatics Inc. have teamed up with Maintenance Connection Canada to build a complete package of GIS (inventory) and Asset Management.
