GTViewer for iOS Version 2.0

It has been over 2 years since GTI began developing GTViewer for iOS, and more than a year has passed since its release.  Version 2.0 will soon be available, and it brings many new features to make GTViewer for iOS even more powerful.

Version 1.0 brought GTViewer datasets to the iOS device (iPhone/iPad) and gave users the ability to operate without the need of a network connection.   Since GTViewer for iOS looks and feels very similar to GTWeb for iOS, the significance of being disconnected from the network sometimes gets lost.  The almost 15 year old code base that drives GTWeb Server and also shared with GTViewer for Windows could not be leveraged on the iOS platform; so, everything had to be created again from scratch.

GTViewer for iOS Version 2.0 provides a multitude of fixes, tweaks, and minor enhancements; it keeps pace with the progression of iOS itself (iOS 5 to iOS 8); and it addresses several user requests.  The most prominent new features are:

• Redlines – Basic redlining support has been added.  Users can now draw and edit rectangles, circles, text, and freehand.   A new server application called GTShare has also been created to manage these redlines.  Users can post selected redlines to the server and can retrieve redlines that other users have posted.   GTShare also supports GTViewer for Window and GTViewer for Android, so redlines can be shared between any of these users.

Draw Redlines on your iPad

See Redlines in GTViewer for Windows

• Raster Backdrop Support – While GTViewer for iOS does not yet support native raster backdrop images on the device, version 2.0 does provide ability to retrieve the backdrop imagery from a GTWeb Server (which does support raster backdrops) for the current view.  Retrieving the backdrop image for your current view requires a network connection to download, but the user can keep a number of these images when disconnected.   Many devices do not have enough storage capacity to hold a full raster backdrop imagery dataset, so this alternative to native support may actually turn out to be more useful in the long run.

Find an area you want to see backdrop Imagery.

Download Imagery for Current View.

Downloaded Imagery is still available offline.

        

• Where Am I – Any tap on the in the map view will display an Attribute Info pop up showing the current location's X/Y and Latitude/Longitude values.  If you are reviewing a feature, this info will be at the bottom of the feature’s attributes.   It is also possible to create custom Where Am I functionality so that a set of polygon features in the data will be searched to see which ones contain the point (similar to the Where Am I functionality in GTViewer and GTWeb).

Standard Where Am I shows Coordinate Info at any point.

Customized Where Am I shows data specific info.

• Driving Directions – Leveraging the power of other applications on the device, Version 2.0 can now kick off the Google Maps app from any point or feature in its map.  Google Maps will then route you from your current location to the specified destination.

Review a Feature, Press Directions button.

Google Maps is launched with feature's location as the destination.

• Developer’s Framework - just as GTViewer for Windows has a set of tools for the developer to create applications with GTViewer functionality, the GTViewer Framework for iOS packages up the code-base used by GTViewer for iOS and makes this functionality available to iOS developers to use in their applications.  This Framework is roughly equivalent to the GTViewer Objects (used with .NET) and provides a set of objects capable of reading a GTViewer dataset.   Full map rendering with panning, zooming, and feature selection 
  are also provided.

GTViewer version 14.0.0.22 is Available

GTViewer version 14.0.0.22 is available.

This update fixes a couple of problems with the new Options/Settings added to the previous version plus adds a new method to the API.

-----------------------
14.00.00.22 - 7/9/18
-----------------------

- FIX - #7464 - Fix to the new Settings Options (View Scrollbars and Toolbar Button sizes).

- NEW - #7465 - New method: SetCoordinateConversionInfo method added.

GTViewer and GTVx with Touch Screens

With Windows 8 and 8.1 machines becoming more widespread, the availability of a Touch Screen is common .  It is also possible to use Windows 7 with a Touch Screen too, so the chances of using GTViewer with a Touch Screen is more and more likely.

Version 14.0.x.21 of GTViewer and 14.0.x.7 of GTVx both provide specific settings to make them run better with a Touch Screen interface.   They have always worked with Windows 8 and 8.1 using conventional inputs (mouse and keyboard), but the scrollbars on the map view window seem to confuse the Touch Screen interface.

In GTViewer, you can now use the Options/Settings dialog to configure 4 different setting values to better use a Touch Screen interface:

1. Change View Scrollbars to NO.
2. Change the Mouse Wheel Increment to a negative value.   This will make a 2 finger pinch gesture zoom out instead of zoom in.
3. Change the Toolbar Button Size to Large, Larger, or Largest.  Making the buttons larger, makes them easier to use with touch.
4. You may also want to set the Selection Tolerance to a higher value since touch is not as accurate as a mouse click.

The View Scrollbars and Toolbar Button Size settings are new to 14.0.x.21.   Mouse Wheel Increment and Selection Tolerance were already available, and you must use the Set as Default button to retain the value beyond the current session.


In GTVx, you can use the following to set the setting values:

   AxGTVX1.ShowScrollBars(0)
   AxGTVX1.SetDataProperty("MouseWheelIncrement", "-1.5")
   AxGTVX1.SetDataProperty("SelectionTolerance", "6")

Make sure to call the ShowScrollBars method before you open any data.


With these settings, you should be able to use a Pinch to zoom in or out in any mode that you can use the moue wheel to zoom in or out.  

A Touch should behave like a mouse click in most GTViewer modes, and Touch and Hold will activate a right mouse click.

GTVx version 14.0.0.7 is Available

Riding Across America with GTSpot (Halfway)

Here is an update on the previous post, Riding Across America with GTSpot.

Dave is over halfway now.

Riding Across America with GTSpot

Riding Across America with GTSpot
by Mike Rogers

When Dave Ryder told me he was going to ride his bike across America I said, “Hey, we have an app for that!” We loaded up his iPhone with our GTSpot crowd sourcing application.  The application allows him to post photo reports along his route so that we can see where he is and what he is looking at.  The GTSpot reports capture his location, a photo, a category and any notes he adds.  We designed GTSpot to allow employees and customers to provide reports of conditions in the field.  It is turning out to be very useful to Dave for the same reasons it is good for a utility.  The report is emailed directly to the responsible party for action.  In this case we show the photos on Google Maps as a pin, but they can also be used with GTViewer, GTWeb, or any other app you want.   Dave does not have to manage the upload of the photos at the end of the day, and the photo and report are immediately available for the folks that are tracking him. It is so easy that Dave is taking all his photos with the application, and he is taking about 20 a day.  If you would like to follow Dave’s blog you can check it out at here.   There is a link to the map on his blog.

Let us know if you would like to know how you can use GTSpot to empower your employees and customers at your utility.  GTSpot works on iOS (iPhone/iPad) and Android (phones/tablets). We can brand the app for your company and help you utilize the data it collects.
