National Atlas and National Map changes

The USGS has announced that the National Atlas will be taken out of service as of September 30, 2014. According to the detailed product availability information, much of the data will be available via the to-be-enhanced National Map system, or as data downloads "at no cost" from Earth Explorer". This transition appears to be mostly a resource realignment (basically reducing the number of sources and web sites they need to maintain. In addition, the USGS has also announced that "[L]ater this year we will deliver these new framework datasets at one million-scale: networked hydrography, updated streams and water bodies …

Scientific American looks at Coordinates

Scientific American posted an overview about tectonic plate movement, datums and geodesy. The article covers a fair amount of ground in some depth, but not so much so that it's confusing. Check it out and contemplate the amount of work that we'll all be doing when the USGS updates the datum in another few years. For those who are curious, Cartographica maintains a large list of datum and datum shift information so that it can accurately overlay coordinates from one system onto another. These calculations aren't trivial and we had quite a time squeezing these conversions into the first version …

Cartographica 1.4.2 compatible with Mavericks

We have been testing against Mavericks since the early betas and the 1.4.2 version of Cartographica works well with it. At this point, we aren't taking advantage of any Mavericks-specific features, but we have found on our test machines that the upgrade is a good performance move, especially for laptops. Other ClueTrust software, such as LoadMyTracks, has also been tested and works fine with Mavericks (excepting, of course, the long-standing issue with the Mac AppStore version of LoadMyTracks and serial devices due to Apple's policy change). Although we haven't tested any of the 1.2.x versions on …

Growing use of OpenStreetMap in Government

We at ClueTrust integrated support for OpenStreetMap into both Cartographica and CartoMobile some time ago because it provides an avenue for public updating and curation that is unequaled and also provides data licensing that allows liberal reuse. We are happy to see the wide range of OpenStreetMap in Government outlined on the OpenStreetMap.US blog. There are lots of opportunities to improve the data set and make your mark on open data, while improving available map data for everyone. For those with little background with the organization, it didn't start in the US, but in Europe, where most Geospatial data …

Cartographica 1.4.2 Available

Cartographica 1.4.2 is now available, and it's got a little bit of everything to it: new features, performance enhancements, and bug fixes. This release ended up taking a bit longer than we expected as we have been working hard to fix the bugs reported in 1.4 and 1.4.1. But, we haven't just been working on fixing bugs, we've also been enhancing the capabilities and performance of the existing capabilities of Cartographica, with improvements in everything from WFS compatibility to execution speed and progress information for many of our analysis tools. I won't take up the …

Cartographica 1.4 and beyond

At ClueTrust, we're proud and excited to deliver version 1.4 of Cartographica into the hands of our customers. This has been a long journey from the last major feature release to this one, and although we have added a lot of new functionality to the software and made many improvements, it became clear to us months ago that something was going to have to change for us to be more responsive to the needs of the market and our customers. To that end, we have been bolstering our automated testing capabilities, enhancing our hands-on testing regime, and changing how …

Cartographica 1.4 is now in beta

We are very pleased to finally make available the first release of 1.4, our largest version of Cartographica to date. Please read these notes if you choose to use this beta version of the software. We will be following up this post over the next few weeks discussing the new features and capabilities of Cartographica 1.4. Beta Test Warnings Warning: Although we have done extensive internal and private beta testing, it is important to remember that this version of Cartographica is still considered to be in testing. Please make sure that you have files that you are working …

Cartographica 1.2.8 ready for Mountain Lion and Retina Display

ClueTrust is happy to announce today the immediate availability of Cartographica 1.2.8. This release fixes a number of small bugs and includes compatibility and feature fixes for both the Retina Display MacBook Pros and Mountain Lion. Full release notes are available on the macgis.com site. The new Retina Display Mac Book Pros are gorgeous, and we're happy to say that things are really looking good on those displays, and with the advent of Mountain Lion's new Gatekeeper system, we have increased security by implementing Apple's new signature system to show that Cartographica comes from us, so you …

US Ag Department looks for input on aerial imagery

As reported in Ag Professional and forwarded along by one of our astute customers, the US Department of Agriculture's Farm Service Agency has put out a public call for comments on how data is collected for requests for Aerial Photography through the NAIP program, which is a great source of raster data for software such as Cartographica. The call for information is specifically expected to help the agency: Determine whether the continued collection of information is still necessary for the proper performance of the functions of the FSA, including whether the information will have practical utility; Assess the accuracy …

Mountain Lion support and the Future of Cartographica

It's been about two years since I made this post about Snow Leopard and ClueTrust's plans to drop support for Leopard (10.5) in versions 1.2 of Cartographica and beyond. Since that time, we've had rapid adoption of Snow Leopard (10.6) and, in the past year, Lion (10.7) by our users (according to those statistics that you hopefully have been allowing us to capture). Earlier this month, we once again attended Apple's WWDC and we learned a lot about how we can take advantage of the new features in Mountain Lion and that Apple has now lowered …

Using MapQuest satellite imagery

MapQuest has recently made available, through information on their developer website, access to their tile servers for OpenStreetMap-style tiles of satellite imagery (mostly from government sources) and their street databases. Because both CartoMobile and Cartographica support customized OpenStreetMap-style tile sources, you can now add these to your maps. Cartographica Desktop Within an existing mapset, add a new live layer by choosing File > Add Live Map… Choose Other OpenStreetMap Server: from the list of sources Type the following into the URL box: http://oatile1.mqcdn.com/tiles/1.0.0/sat Click Add A new layer named OpenStreetMap Live will …

CartoMobile: Your data in your hands

There are a lot of mobile mapping applications for iOS, and even with that as a backdrop, we decided to develop and release CartoMobile because we saw a place for a sophisticated and easy-to-use App for creating and accessing your geospatial data from anywhere. We're often asked what sets CartoMobile apart from other mapping Apps for iOS. Basically, we believe that you should be able to have easy access to your data on the go. Here's how we have done this: No Need to Import/Export — CartoMobile handles shapefiles and raster files directly. There's no need to do any coordinate …

CartoMobile 1.2 released with MrSID® and more

Today, we're pleased to announce that CartoMobile® 1.2 has hit the AppStore with a number of new features and a bunch of bug fixes and usability tweaks. The biggest advance in 1.2 is the addition of MrSID and JPEG2000 image formats for Raster Imagery. This adds to our already robust selections of: TIFF, GeoTIFF, JPEG, and ECW, to create a very complete selection of image formats for offline access. As with previous formats, you can copy these directly to the device using iTunes and add them to your Map by choosing Import Raster Image. To accompany this addition …

Free data available from Natural Earth

Many of us spend a lot of time looking for data to use for maps and I wanted to mention Natural Earth, a site whose tag line "Free vector and raster map data at 1:10m, 1:50m, and 1:110m scales" pretty much says it all. There's a lot of stuff here, and it's good for many purposes, and it's truly free, as in Public Domain. The data can be dragged and dropped directly into Cartographica for use in your own projects, without any licensing issues, which is fantastic.Further, there are both raster and vector data sets, so …

Summarizing Point Data on a Polygon Layer

Occasionally it is necessary to summarize the data from a layer of points based on containment within a polygon layer. This article presents a relatively straightforward way to do this with Cartographica. The solution to this problem requires the use of both an internal command and a small AppleScript, which we will provide. This simple script can be modified for your individual needs to apply basically any formula, but in the example case, it provides the sum of the values of a single column in the point dataset. At the end of this piece, we'll discuss some easy adaptations of …

Farewell and Thanks, Steve Jobs

Yesterday we learned of the death of a man who had a profound effect on the course of my life and the life of this company. I am sure that this sentiment has and will be reflected many times, but it makes it no less true in our case. Our thoughts and prayers go out to his family and all of those whose lives were touched by him. I never knew the man personally, although I stood in the same room with him many times. I have owned at least one Macintosh since 1984 (including a dark period where I …

CartoMobile 1.1 released

ClueTrust is pleased to announce the immediate availability of CartoMobile® 1.1 on the App Store! New features include adding lines and polygons, easy use of Raster data as base maps, multiple projection support, and more! Version 1.1 of CartoMobile is a huge release for us, starting with the name change. ClueTrust has decided to re-brand Cartographica Mobile as CartoMobile, both because the name "Cartographica Mobile" just doesn't fit well in the app screen on the iPhone, and also to differentiate its place as a field data tool, as opposed to a full-fledged GIS, like Cartographica. CartoMobile 1.1 …

Cartographica 1.2.4 available now

ClueTrust is happy to announce the immediate availability of Cartographica 1.2.4, a bug fix release for Cartographica 1.2. This release contains no new features, and fixes a handful of bugs (some peculiar to OS X 10.7 Lion). The full release notes are available at MacGIS.com.
