The Future of Geospatial Imagery Collection Analysis Exploitation and Exchange

Geospatial intelligence has never been more important to enabling and enhancing a wide range of national and international missions as it is today. As the sources of geospatial data are increasing, expect there to be a decrease in the concern over access and availability of data over the next five to ten years. In terms of data security, future innovations within the industry to secure the influx of data are anticipated.

The Future of Geospatial Imagery Collection Analysis Exploitation and ExchangeGIS is making a crucial difference to National Security in different environments, which ones do you think are being impacted most by the application of GIS?

From tackling the terrorist threat, to the refugee crisis, to the management of natural resources, and even planning for major sporting events like the Olympics, you’ll find GEOINT at the forefront.

The applications for GIS reach far and wide. These results show us that beyond global security, GIS also has an important role to play in mapping natural disasters and planning and managing natural resources. This is particularly important in regard to increased water shortages in the face of rapid population growth worldwide.

Bathymetry of Lake Ontario

Bathymetry of Lake Ontario

Bathymetry of Lake Ontario

Bathymetry is used to measure water depths to help model physical underwater terrain found beneath large bodies of water. Similar to the same way that LiDAR models are represent 3D features (or relief) of land terrain, bathymetric maps illustrate the terrain or land that is located under large bodies of water. Color ramps created from depth contours or isobaths help make the variations in relief easier to see.

“High-resolution digital bathymetry makes possible meaningful quantitative estimates of available habitats for fish and other living organisms. In other lakes these estimates have been used to formulate regulations intended to prevent overfishing. Conversely, Great Lakes bathymetry is much in demand by anglers as an aid in locating the most promising areas for fishing.”

The Bathymetry of Lake Ontario was the third poster map released by National Oceanic and Atmospheric Administration (NOAA) depicting highly detailed bathymetry data ( at 2 meter contour interval) of the Great Lakes.

How to Get Ontario Topographic Data

Looking for Ontario Topographic Data?

Recently, someone contacted me looking for information on where they could find Ontario topographic data for the Thunder Bay area, so I assumed that they must have already checked the Canadian data page and suggested that they check out the Ontario Basic Mapping website (OBM).

The Ontario Basic Mapping (OBM) site by the Geography Network is a great online resource with simplistic interactive interface that provides users tools to create customized map views and the ability to download various topographic base mapping data for the entire Province of Ontario. The site contains GIS layers created from 1:10,000 base maps from the Ontario Ministry of Natural Resources that people can download including layers for transportation, water, municipal, elevation, parks and conservation areas. The portal created with ArcIMS makes it pretty easy to use and a convenient way to obtain mapping data in a variety of formats for virtually any area of interest in Ontario.

Ontario Topographic Data - Ontario Base Mapping Download Site

However, that person replied back to me a few days latter telling me that the site was only an online web map viewer and they needed actual data to use in a GIS, and wanted to know if I had any other sources of mapping information for Northern Ontario.

Now, I thought that the e-mail was a little strange since I have used data from the Ontario Basic Mapping web site before while planning various aerial surveys in Northern Ontario, so I decided to go check out the web site to see if the downloading data feature that I had used had been removed. Turns out the site is still the same, it can be used as an online web map viewer to customize and print maps but the downloading option still exists providing the ability to download the map layers in the viewer to use with your own GIS software packages like ArcMap or MapInfo.

It seems like a pretty simple mapping application to me but maybe it is not as obvious as some people need it to be, so I decided to share some of the notes on downloading topographic base data from the OBM site that I provided to them, in case others have trouble figuring how to download the data as well (And summarized in the video at the bottom).

The OBM site is an ArcIMS site with a simplistic look and an interactive interface that provides users with tools to create customized map views and the ability to download the various topographic base mapping data in the map window. If you are not interested in downloading GIS layers but still want to make some maps then like most typical map viewers, they also provide printing options where you can create either paper or digital PDF maps.

Ontario Topographic Data - Ontario Base Mapping - Thunder BayWhen you first open the viewer you are zoomed out to the full extent of the province with mapping tools represented by icons on your left and accessible data layers on the right hand side. Using the AOI icon, you first need to define an area of interest that will zoom the map window into your specific area, populating the map window with more detailed GIS layers and features.

From the list on the right hand side, you then select the visible layers that you wish to download. Next using the FME icon from the tools on the left hand side, a window will open up prompting you to log-in, create a free user name and password (or enter your existing log-in) and then a download options window will appear.

You then need to click a check box to agree with the license terms and click the Download Data button to continue. Finally another window with instructions for acquiring the data in a variety of formats (e.g. SHP, DWG, DXF etc.) and in either Latitude / Longitude or Lambert Conformal Conic coordinate system. Then there will be one final window with a message telling to check your e-mail for a message.

You will then get a machine-generated e-mail from the Geography Network with a custom download link with the Ontario topographic data layers that you specified for your area of interest that you defined. And that is all there is to it, so if you are looking for Ontario topographic GIS data layers to download or  just want want to create online maps then the Ontario Basic Mapping (OBM) site could help you out.

If you know of other Ontario data sources that I have not yet added to the Canadian data  collections then let me know about it and I will add it to the site.

Questions You Should Answer Before You Buy A Laser Scanner

Critical Questions To Ask About Laser Scanners

Before You Buy Laser ScannersChoosing 3D laser scanners should be a quantitative process with significant ramifications for your project deliverables, project workflow, resources, personnel, time and cost.

Land Applications of Radar Remote Sensing

Land Applications of Radar Remote Sensing

Synthetic-aperture radar (SAR) is a type of radar data that can be used to generate 3D images of terrestrial object, such as topography. SAR images have multiple applications in remote sensing and topographic mapping of surfaces.

Land Applications of Radar Remote Sensing [Free Book]The images are created from radio pulses that are transmitted towards a target area, then received and recorded. The pulse waves are usually transmitted and received with a single beam antenna, and the wavelengths used can be anywhere from a meter to a few centimeters.

The book Land Applications of Radar Remote Sensing demonstrates the use of SAR with topography and land cover. The authors go into extensive details on speckle and adaptive filtering, as well as digital elevation models (DEMs) and terrain modeling.

QMap – A field data collection program using QGIS

QMap - A field data collection program using QGIS

QMap – A field data collection program using QGIS

QMap is a field data collection application built using QGIS and python plugins. It is very similar to QGIS but with an interface that makes it easier for most people to use for data collection in the field and was designed to work with windows based tablet devices. Custom forms are built using Qt Designer and follows a convention based approach in order to save configuration. The application also supports QGIS project files (.qgs) so that you can easily use it with  your QGIS  desktop mapping projects.

To download the application or get more info about QMap go to http://nathanw2.github.com/qmap/
