NASA NEX wins the 2014 HPCwire Readers' and Editors' Choice Award
Congratulations to the NASA NEX Team! They have won the 2014 HPCwire Readers’ & Editors’ Choice Award for the Best Data-Intensive System (End User focused). See the article here: NASA Earth Exchange (NEX) Platform supports dozens of data-intensive projects in Earth sciences.
The NASA Earth Exchange (NEX) platform supports dozens of data-intensive projects in Earth sciences, bringing together supercomputers and huge volumes of NASA data, and enabling scientists to test hypotheses and execute modeling/analysis projects at a scale previously out of their reach. NEX-supported applications range from modeling El Niño, creating neighborhood-scale climate projections, assisting in crop water management, and mapping changes in forest structure across North America, to mapping individual tree crowns at continental scale as a foundation for new global science at unprecedented spatial resolution. NEX’s OpenNEX challenge ties in to White House initiatives, including Open Data, Big Data and Climate Data, which advance national goals to address climate change impacts and include competitions and challenges to foster regional innovation.
The GIF has been partnering with NASA NEX, and developing a framework to bring NEX data and analytical capabilities into HOLOS.
Map of open source map resources (as of 2012)
From this great paper I just came across:
Volume 39: 136–150.
and The 2012 free and open source GIS software map – A guide to facilitate research, development, and adoption. Computers, Environment, and Urban Systems.From the paper: "Over the last decade an increasing number of free and open source software projects have been founded that concentrate on developing several types of software for geographic data collection, storage, analysis and visualization. We first identify the drivers of such software projects and identify different types of geographic information software, e.g. desktop GIS, remote sensing software, server GIS etc. We then list the major projects for each software category. Afterwards we discuss the points that should be considered if free and open source software is to be selected for use in business and research, such as software functionality, license types and their restrictions, developer and user community characteristics, etc. Finally possible future developments are addressed."
/span>Web mapping of high res imagery helps conservation
One of our collaborators on the Sonoma Vegetation Mapping Project has sent work on how web mapping and high resolution imagery has helped them do their job well. These are specific comments, but might be more generally applicable to other mapping and conservation arenas.
- Communicating with partnering agencies.
- In the past year this included both large wetland restoration projects and the transfer of ownership of several thousands of acres to new stewards.
- Articulating to potential donors the context and resources of significant properties that became available for purchase.
- There are properties that have been identified as high priority conservation areas for decades and require quick action or the opportunity to protect would pass.
- Internal communication to our own staff.
- We have been involved in the protection of over 75 properties, over 47,000 acres. At this time we own 18 properties (~6500 acres) and 41 conservation easements (~7000 acres). At this scale high quality aerial imagery is essential to the size of land we steward and effective broad understanding. The way it is served as a seamless mosaic means it is available to extremely experienced and intelligent people who find the process of searching and joining orthorectified imagery by the flight path and row cumbersome or inefficient.
- Researching properties of interest.
- Besides our own internal prioritization of parcels to protect, I understand that we receive a request a week for our organization’s attention towards some property in Sonoma. Orienting ourselves to the place always includes a map with the property boundary using the most recent and/or high quality imagery for the parcel of interest and its neighbors. This is such a regular part of our process that we created a ArcGIS Server based toolset that streamlines this research task and cartography. The imagery service we consume as the basemap for all these maps is now the 2011 imagery service. This imagery is of high enough resolution that we can count on it for both regional and parcel scale inspection to support our decisions to apply our resources.
- Orienting participants to site.
- Our On the Land Program uses the imagery in their introduction maps to help visitors on guided hikes quickly orient to the place they are visiting and start folding their experience and sense of place into their visit.
- Complementing grant applications.
- Grants are an important part of the funding for major projects we undertake. High quality imagery facilitates our ability to orient the grant reviewer and visually support the argument we are making which is that our efforts will be effective and worthy of funds that are in short supply.
- Knowing what the resources on a property are is an essential part of thoughtfully managing them.
- In one example we used the aerial imagery (only a year old at the time) as a base map for botanists to classify the vegetation communities. These botanists are not experts in GIS, but by using paper maps with high resolution prints in the field they were easily able to delineate what they were observing on the ground on features interpreted in the photo. We then scanned and confidently registered their hand annotations to the same imagery, allowing staff to digitized the polygons that represent the habitat observed. These vegetation observations are shared with Sonoma County and its efforts to map all the vegetation of Sonoma County.
- Conservation easement monitoring makes extensive use of aerial imagery.
- In some cases we catch violations of our easements that are difficult to view on the ground, for example unpermitted buildings by neighbors on the lands we protect, illegal agriculture or other encroachment. It is often used to orient new and old staff to a large property before walking their and planning for work projects that might be part of prescribed management.
- The imagery helps reinforce our efforts to communicate the challenge to preserve essential connectivity in the developed and undeveloped areas of Sonoma County.
- In the Sonoma Valley there is a wildlife corridor of great interest to us as conservation priority. Aerial imagery has been an important part of discussing large land holdings such as the Sonoma Developmental Center, existing conserved land by Sonoma Land Trust and others, and the uses of the valley for housing and agriculture.
- Celebration of the landscape cannot be forgotten.
- We often pair this high quality aerial imagery with artful nature photography. The message of the parts and their relation to the whole are succinctly and poetically made. This is essential feedback to members and donors who need to see the numbers of acres protected with their support and have the heartfelt sense of success.
We look forward to the continued use of this data and the effective way it is shared.
We hope that future imagery and other raster or elevation data can be served as well as this, it would benefit many engaged in science and conservation.

Workshop on Oct 19: Planet Mapping: The Science of 3D Maps
Planet Mapping: The Science of 3D Maps. Find out what tools and techniques are enabling today’s modern cartographers to render 3D maps.
Location: swissnex San Francisco
730 Montgomery St., San Francisco, 94111
Our world is constantly being captured through GPS, cameras, satellites, and scanners and rendered by algorithms into navigable maps of Planet Earth. But how are 3D maps really made? How is the data collected?
Hear from some of the hottest startups in the field about the science and technology behind 3D map making—from data collection, to processing, to display—and discover how you can make your own 3D maps.
During the event, enjoy the visual stimulation of the PLACEMAKERS exhibit on view at swissnex San Francisco.
Program:
- 6:30 pm doors open
- 7:00 pm intro
- 7:10 pm talks + Q&A
- 8:45 pm networking reception
