What is Blue Marble GeoTalks 2020?

In spring of 2019, Blue Marble Geographics® launched its first online conference, GeoTalks, to replace its user conferences, which had been held at locations around the globe. Not only did the virtual format of the day-long GeoTalks expand accessibility to a wider audience, it also opened the door for more geospatial professionals from all over the world to participate and share their expertise as speakers. In its inaugural event in 2019, GeoTalks had more than 800 registrations. Below is a breakdown and sneak peek of what GeoTalks will include in 2020.

Presentations by professionals from a variety of geospatial industries and backgrounds

At the 2020 GeoTalks, speakers from all over the world and from a wide range of backgrounds will be participating. Here is a peek at who will be presenting this year:

Ben Follett, a Principal Engineering Geologist with WSP, Australia

Ben Follett

Ben Follett  will present on a workflow using Global Mapper® to assess the effects of pipeline construction. This GeoTalks presentation will cover attribute calculation, various digitizing tools, contouring, and illustrating slopes as low as fractions of a degree in order to identify structures that may be affected by the dewatering process in construction.

Walter Payne, a Space Intelligence Analyst with the Defense Intelligence Agency USSTRATCOM

Walter Payne

Walter Payne will give a presentation on “An Unexpected Discovery”, in which he will share the role he played in a research project that focused on the Pena de Juaica, a mountain 3,209 meters high, located in the Colombian town of Tobio.

The goals of this research project were to identify carved figures and anthropomorphic forms, and to locate caves for exploration. During this expedition, he used Global Mapper and the Lidar Module’s Pixels to Points® tool to process drone-captured images of the base of Pena de Juaica. The resulting photogrammetric data helped Walter, historian Ashley Cowie, and a team of Ancient Origins explorers discover an “outlier platform” used by the indigenous Muisca people for lunar astronomy.

Jeff Howry, a Research Fellow at the Harvard Semitic Museum

Jeff Howry

Jeff Howry will demonstrate how the application of lidar on two continents reveals distinctly different historic landscapes.

In New England, the pattern of agriculture in the 17th and 18th centuries becomes apparent when imagery of stone walls is analyzed. Following the abandonment of farms beginning in the 1850s, much of the landscape which was previously open land has become reforested with dense hardwood species. Lidar readily presents the stone wall boundaries of the field system used by New England farmers in their land-intensive agricultural practices. In the area that was historic Palestine, sites occupied several thousands of years ago, reveal their major landscape structures through lidar.

Akpata Sylvester Balm Mifueah, a Ph.D. candidate in Geoinformatics and Surveying at University of Nigeria

Akpata Sylvester Balm Mifueah

Akpata Sylvester Balm Mifueah, who also serves as a Project Coordinator with Reddfox on NESP Nigeria, will present on the extreme importance of a healthy infrastructure to maintain safe roads and constant power supply to Nigerians.

Akapata will deliver a presentation on using Global Mapper Mobile®, geodetic principles, remote sensing, and GIS techniques to track and identify road and powerline conditions. He used the mobile app for tracking, arable land types, roads and power transmission lines in Nigeria, and processed and validated the data using remotely sensed images in Global Mapper desktop. The results were coordinates of each tracked point, and a database that shows records of roads and power line conditions.

Rudy VanDrie, a Planning Engineer in Hydrology with the Central Coast Council, Wollongong City Council and Balance Research & Development

Rudy VanDrie

Rudy VanDrie has been working in the flood modelling space since 1987. His GeoTalks 2020 presentation will highlight the benefits of using Global Mapper for flood model development and as used in a real world workflow. Flood modeling is becoming more and more detailed, as experts move away from using fixed grid coarse models and toward flexible meshes with very fine detail, requiring better representative terrain data. Global Mapper has become a standout tool for cleaning and merging data, and formulating the best possible terrain for flood modeling.

Kelsi Schwind, a Coastal and Marine System Sciences student at Texas A&M University-Corpus Christi

Kelsi Schwind

Kelsi is the 2019 winner of the Blue Marble Academic Scholarship, and a Coastal and Marine System Sciences (remote sensing emphasis) student at Texas A&M University-Corpus Christi.

Kelsi will present on her research, which integrates structure-from-motion (SfM) data, airborne topobathymetric lidar-derived data, and GIS techniques to assess the impacts of Hurricane Michael on Little St. George Barrier Island off the coast of Apalachicola, Florida.

What’s new in Global Mapper v21.1?

What we at Blue Marble Geographics® call a “dot release” — Global Mapper® v21.1 — is now available and it comes with new features and improvements. In this blog entry, we list the most significant new features in our accessible and easy-to-use GIS software.

Raster Reclassification tool in Global Mapper v21.1Chelsea E | Projections

The Raster Reclassification tool

The new Raster Reclassification tool is used to reclassify raster data for land cover analyses. Reclassification may be necessary when raster values need simplification or translation in an analysis. The tool also allows users to simplify information by grouping similar data together, for example, grouping all types of high vegetation together as “forest”.

Other reasons for using the Raster Reclassification tool are to set values to a common scale or to set specific values as “no data” to remove them from the analysis completely.

A built-in, premium access to online Blackbeard Tanuki

With a subscription, users can now access Blackbeard Tanuki’s oil and gas data services, which provides pipeline, well, and lease information. This is valuable data for oil, gas, or mineral investors; oil and gas lease owners looking for neighboring ownership; oil and gas E&P companies looking for land to lease, and landmen seeking a point of departure for oil and gas exploration.

Raster Transparency tool in Global Mapper v21.1

Improved Raster Transparency tool

This tool allows users to render multiple colors as transparent in raster layers. This function is ideal for hiding non-imagery, background pixels or white, cloud areas in satellite imagery. It can also be used to make certain elevation ranges transparent in a terrain data, perhaps to reveal another data layer underneath.

Improved processing time for Batch Conversion/Reproject tool

The Batch Conversion/Reproject tool has been multi-threaded in Global Mapper v21.1. This means that the batch work is divided between the cores of the CPU. In other words, the batch process in v21.1 is faster because it is using multiple brains instead of one! This speed improvement was added for the many Global Mapper users who batch convert image tiles or lidar tiles to change either the format, projection, or both.

Speed improvements and efficiency improvements

The processing time for the Batch Conversion/Reproject tool has been improved significantly, due to the fact that the process is now multi-threaded. Other aspects of the software that have been made more efficient through multi-threading include the rendering of the 2D map view and the Viewshed Analysis tool.

Additional speed improvements include operations such as rendering large ECW files or creating elevation grids with large gaps to fill.

Download or upgrade your Global Mapper today

We pride ourselves on providing multiple updates each year to keep our software fresh and cutting-edge. Download or upgrade your copy of Global Mapper to version 21.1 today to take advantage of the latest new features.

How to publish and share maps with Global Mapper and MangoMap

Beginning with version 21 of Global Mapper®, users have the option to publish maps directly from the desktop GIS software to the online web mapping service, MangoMap. This functionality is subscription-based and is enabled by activating the MangoMap extension.

MangoMap is a browser-based web mapping service that provides a simple and efficient way to share geospatial data with anyone, on any device. Setting up an online map site through Mango requires no specialized web development skills or expensive servers and the entire process takes only minutes.

This blog entry lists the steps required to publish data from Global Mapper, and customize and share it through MangoMap.

Once users have chosen their export settings and map display options, their map is sent to their MangoMap account where their data and styling are immediately ready for viewing.

Step One: Register a MangoMap account

First things first: In order to publish a map to MangoMap, Global Mapper users have to register a MangoMap account to activate the extension. This is a simple process that involves clicking the MangoMap button in the Global Mapper interface, and setting up an account with their Blue Marble login information.

Once an account is set up, users can begin publishing maps online immediately with a free trial of MangoMap!

MangoMap is ideal for publishing and sharing single-focus maps, not necessarily for maps with several layers of data. It does, however, include a map portal where users can publish a gallery of single-focus maps.

Step Two: Click the MangoMap button to publish

It’s as simple as that.

The MangoMap button in Global Mapper prompts users to name and describe their data, and choose the necessary display settings. Once these settings are defined, users click “OK” and their map is sent to their MangoMap account. The data and styling of their map is immediately ready to be viewed online.

The attributes of a parcel feature are displayed in MangoMap. Users can easily activate tools that best suit the purpose of their data in MangoMap.

Step Three: Customize tools and style settings

In MangoMap’s administration interface, users can choose to activate tools that best suit the purpose of their map. They can bookmark map features to find more easily later, and share specific items with colleagues. They can search by specific attributes, add layers, and turn on Google Street view for an alternative visualization. Users can also customize their maps by adding a logo, or changing the colors to match a brand.

MangoMap’s blog entry on Web Map Customization goes into far more detail on how users can design their maps online.

MangoMap users can share specific map features easily.

Step Four: Define map access settings, and share

Just as users can customize tools in their maps, they can also define their maps’ access settings. Users can make their data public allowing anyone to access; hidden, for anyone with a secret URL; password-protected; or internal, for only authorised users.

Sharing a map is as easy as copying the map’s URL in the web browser and sending it to a colleague. Depending on the access settings, the recipient of the map URL will be prompted to enter a password if the map is password-protected, or to login if the map is internal.

Bridging the gap between desktop and web mapping

Like Global Mapper, MangoMap is designed to be easy and intuitive for both the advanced and novice GIS professional. It integrates seamlessly with Global Mapper, making it the perfect solution for multi-platform map sharing for efficient collaboration.
