XMap Q & A

What is the function of the Magic Wand Selection tool in the XMap Toolbar? It is always grayed out, even after I make a layer active.

The Magic Wand Selection tool was added to XMap for some very specific applications and it requires that several prerequisites are satisfied before it becomes available.

The object of the tool is to allow the concurrent selection of multiple line segments that are connected and share a common attribute. This provides the means to verify that the particular attribute has been consistently assigned for each selected segment and to ensure that the line segments are actually connected without any breaks. It also simplifies the process of editing attributes as all sections of the line can be updated simultaneously.

The Magic Wand Tool is essential for DeLorme’s corporate road and street data management process. Technicians are able to quickly ascertain whether roads, which are typically represented in the database by many individual line segments, are connected and that each segment has the correct road label. DeLorme software depends on this verification of connectivity and label consistency to ensure that the route planning tool provides the optimal directions and to guarantee that address searches return accurate results.

Tab Tip

Using a URL Field to Provide Direct Access to GIS Datasets from within XMap

Before jumping headlong into a series of step-by-step instructions that will ultimately achieve the outcome stated in the heading of this article, it would be wise to consider the end product as a means to provide a semblance context for the required steps.

The XMap OpenSpace layer that is available for download here contains a grid covering a portion of Southern Maine, the hinterland of DeLorme’s corporate headquarters. If you import the layer into XMap and zoom to one of the grid tiles, you will notice each tile is labeled “Download” and that this text is an active URL or link. The URL triggers the download of high-resolution orthoimagery for the selected tile in MrSID format. Click one of the links and you will be offered the option to save the corresponding Zipped MrSID file on your local hard drive. Unzip the file and, using the Map Data tab in XMap, add the image to your current project. This is an example of the use of the URL field within XMap for accessing remote data for a selected geographic area.

Coming Soon! The All New Earthmate PN-40 GPS

The perfect complement to XMap, this ground-breaking handheld GPS receiver is scheduled for release in mid November. Early reviews suggest that the PN-40 has raised the bar for handheld GPS receivers and has established the benchmark against which all other devices will be measured.

The incredibly fast duel-core processer is ideally suited for rendering aerial imagery, GIS layers, or any other map you choose to transfer to the device. Incorporating a high-sensitivity 32-channel STMicroelectronic Cartesio chipset, the PN-40 quickly locks in and retains your precise position, even under the most challenging conditions. Its data collection capabilities are ideally suited for cataloging field locations and for integration of this data into a GIS. The list of features and functions that have been engineered into the PN-40 is truly astounding:

  • On-road and back country routing
  • Incredibly fast map redraws due to a new Dual Processor
  • Displays an array of data types, both raster and vector
  • Includes a 3-axis electronic compass and barometric altimeter
  • Ofers 500 MB of internal Flash memory for map storage and supports up to 32 GB High Capacity SD cards

Where on Eartha?

For the first time in the history of the Where on Eartha Challenge , there are two acceptable responses for September’s country and capital question. Virtually all respondents recognized Sri Lanka as the country in the image but there was some dispute as to the capital city. The majority of the emails indicated that Sri Lanka’s capital is the city of Colombo, which was accepted as it generally considered to be the commercial capital of the country. However, in the early 1980s the administrative functions were moved to the neighboring city of Sri Jayawardenapura-Kotte, or simply Kotte, which therefore serves as the official national capital.

First correct response selected randomly from those who provided either of these answers belongs to Dave Alderks, who works as a geologist for Hilliard Energy in Midland, TX. Dave will shortly be receiving a copy of XMap 6.1 Professional with a USB GPS receiver.

This month, the satellite image shows a landlocked country where the geopolitical boundaries appear to be aligned with patterns in land cover and vegetation. If you think you know the name of this country and its capital, send your response in an email to before November 30, 2008, and you could be the next XMap winner.

Did You Know...

Did you know that users of XMap 6 can now access DeLorme’s online Map Library through a subscription service that offers unlimited downloads of a variety of map types for a full year?

For many years XMap has offered the ability to select and download aerial imagery and USGS 1:24,000 series quad maps through the Netlink tab for a per square kilometer fee. Now with the new Map Library subscription service, you can download as much imagery as you require for a flat fee of $29.25.

Available datasets include:

  • Black and white aerial imagery at 1-meter resolution
  • Color imagery at either 1- or 2-meter resolution
  • Satellite imagery at 10-meter resolution
  • USGS 1:24,000 quad maps
  • NOAA nautical charts
  • Color imagery at 30cm resolution (for selected urban areas)
