The processes of mobilization of land for infrastructures of public and private domain are developed according to proper legal frameworks and systematically confronted with the impoverished national situation as regards the cadastral identification and regularization, which leads to big inefficiencies, sometimes with very negative impact to the overall effectiveness.
This project report describes Ferbritas Cadastre Information System (FBSIC) project and tools, which in conjunction with other applications, allow managing the entire life-cycle of Land Acquisition and Cadastre, including support to field activities with the integration of information collected in the field, the development of multi-criteria analysis information, monitoring all information in the exploration stage, and the automated generation of outputs. The benefits are evident at the level of operational efficiency, including tools that enable process integration and standardization of procedures, facilitate analysis and quality control and maximize performance in the acquisition, maintenance and management of registration information and expropriation (expropriation projects). Therefore, the implemented system achieves levels of robustness, comprehensiveness, openness, scalability and reliability suitable for a structural platform.
The resultant solution, FBSIC, is a fit-for-purpose cadastre information system rooted in the field of railway infrastructures.
FBSIC integrating nature of allows: to accomplish present needs and scale to meet future services; to collect, maintain, manage and share all information in one common platform, and transform it into knowledge; to relate with other platforms; to increase accuracy and productivity of business processes related with land property management.

"SPL provides the most efficient approach to rapid, high-resolution 3D mapping. SPL requires only one detected photon per ranging measurement, as opposed to hundreds or thousands of detected photons per ranging measurement for conventional or Geiger Mode airborne LiDARs. The higher efficiency of the SPL offers more 3D mapping capability in terms of swath, spatial resolution, acquisition time and density of range returns. Sigma's ability to rapidly deliver 3D data over thousands of square kilometers is changing the way we observe and analyze Earth.
Single photon sensitive 3D imaging LiDARs have multiple advantages relative to conventional multi-photon LiDARs. Their high efficiency enables orders of magnitudemore imaging capability for a given laser power-receive aperture product. In our Single Photon LiDARs (SPLs), single photon sensitivity is combined with timing receivers having nanosecond recovery times and a multistop timing capability per pixel. These characteristics enable our LiDARs to operate under conditions of full solar illumination and to penetrate semiporous obscurations such as vegetation, ground fog, thin clouds, etc. Also, the use of green (532 nanometer) laser proves to offer additional capability for water penetration (bathymetry) as the SPL is able to routinely measure the surface of the water as well as the topography below the water."
It All Comes Down to Communicationby Brenda Wolfe on June 23, 2015
Five story maps show how governments can increase awareness and inform the public on matters of resilience and sustainability.
“It all comes down to communication,” I thought to myself as I imbibed the words of mayors and other elected officials at the National League of Cities’ Resilient Cities Summit this past May.
For two days, I had the pleasure of listening to eighteen city mayors and executives express their desires for their cities to be more sustainable and resilient. They also articulated their frustrations about the roadblocks that seemed to inevitably arise. I came away with little desire to ever be an elected official (tough job!), but also with a strong desire to help them. But how?
In this video I use ArcMap 10.1 with a 4 band Aerial Photo (RGBiR) to calculate the Normalized Difference Vegetation Index (NDVI), a graphical indicator that can be used to analyze remote sensing measurements to assess whether the target being observed contains live green vegetation or not. I use Spatial Analyst extension along with Raster ...
OK so to start with if I have aggrieved any 'general' IT people out there- the title of this and the content is firmly 'tongue in cheek' and is meant to make GIS people grin with a bit of humour rather than put you down. Also I realise that GIS is in many respects a branch of IT, but we GIS folks sometimes enjoy having a pop at our bigger IT cousins so just take it with a smile (maybe the title should have been GIS is the coolest branch of IT- but hey it's just a headline to grab some attention
It’s important to approach problems in a way that serves every stakeholder. Esri’s ArcGIS platform makes that possible by supporting all major government workflows. (Think: data collection, analysis, what-if scenarios, operational awareness, field operations, civic engagement, and more).
In this post we discuss what we learned from a failed ArcGIS implementation.
"Lesson learned 1: Do not move from the planning phase until you fully and COMPLETELY UNDERSTAND the problem/vision. In our case our final documented plan, though thorough and divided into logical phases, was incomplete because the full translation of need to solution had not been made.
Lesson learned 2: Spend as much time in the data phase as possible. Make sure the client understands and are on-board with the work needed to put the required data in place.
Lesson learned 3: Education is ongoing. That is a given. Its a key area of value we bring to all our clients. We worked hard with this particular client around education. The fact we had to work so hard here should have raised some red flags on our end. In hindsight we should have seen this as an area of concern, maybe requesting more or different technical staff on their end to be involved.
Lesson learned 4: Upfront, if you believe a custom solution will be needed, emphasize that fact, and repeat it often."

"In light of its National Health Plan, Portuguese Directorate-General of Health has developed a web-based GIS called GeoSaúde to enable access of geospatial health data at national and regional level.
Introduction and Background
Reducing avoidable health differences among groups of individuals, health inequities, has been classified by the World Health Organization as an issue of justice and human rights in addition to health.The aim of the Portuguese National Health Plan (NHP) is to promote health equity in Portugal  - hence, nine priority health programs (PHP) were created to address conditions which contributed most to the burden of disease in Portugal .The NHP and PHP developed a large number of indicators to monitor progress and results were published annually in a variety of paper-based reports.
A web-based Geographic Information System (GIS) is an excellent way to illustrate and draw attention to national and regional differences in health indicators because information on the internet is widely accessible. Furthermore, maps are easy to understand and remember due to their simplicity. Usability and visual communication are important components of map design and subject of study by cartographers and web designers.
Features define the way users explore data in a web-based GIS platform and must be taken into account in the development stages.
To respond to the demand for information in light of the NHP, the Portuguese Directorate-General of Health developed a web-based GIS called GeoSaúde. The objective of the present paper is to describe the development of GeoSaúde in terms of content, features and usability."
The U.S. government is helping to guarantee the future of GIS by investing billions of dollars in geospatial education. The hope is that this funding will go towards developing a workforce that is able to use geographic information in order to solve local, national, and global problems. Of source, the [...]
If you want a little help deciding which map projection you should use for your current map project then you should use the Projection Wizard.
This map projection guide allows you to select the extent of the map view you are working with by outlining the area on a Leaflet map. Once you've highlighted your map bounds you can choose a distortion property (Equal-area, Conformal, Equidistant or Compromise).
The Projection Wizard will then suggest which map projection you should use depending on the extent and the distortion property of the map. The suggested projections are based on 'A Guide to Selecting Map Projections' by the Cartography and Geovisualization Group at Oregon State University.
A PROJ.4 link is provided next to each suggested projection, which opens a popup window with a PROJ.4 library. Once you've settled on your map projection you might want to check-out theProj4Leaflet plugin for using projections supported by Proj4js with Leaflet powered maps.
