/ / Project, Public, Research, Teaching / , / 1 minute of reading

Besides conducting a comprehensive needs assessment that helps adequately define the user needs and identify the available resources within the NSO and in the country, particularly the funding requirements, we need to consider critical factors to succeed in a full digital GIS-based census program. Chief among these factors are: ensuring senior management commitment to developing a long-term digital program; building the technical and human capacities required for sustaining the GIS-based systems and databases and setting […]

According to Dangermond, the top five trends in GIS technology today are as follows: Location as a service Advanced analytics Big data analytics Real-time GIS Mobility Dangermond continues: “The last leap in computing was the shift from the server to the cloud. Software as a service (SaaS) opened a world of opportunities for GIS, as shared map services like the World Imagery basemap are no longer separate from the unique services offered to users. GIS

Database Modeling

Using abstraction from concepts by humans to their implementation in the machine, database modeling relies generally on a three-tier model: A conceptual model involving the identification of the geographic features to be included in the database as entities/objects, the definition of their attributes, and how they relate to one another. An abstraction and objective representation of the real world independent from the DBMS software to be used. A logical model, a resulting outcome from the transformation

Geocoding (geographically enabling unit records) is defined as the process of finding associated geographic coordinates (expressed in latitude and longitude) from other geographic data for the statistical units, such as street addresses or postal codes. (Geocoding is a way to ensure that the data “knows” where it is.) In other words, geocoding involves taking location information for these statistical units (such as address) and linking this information to a location coordinate (i.e., x,y,z coordinates) and/or

“A very common type of spatial analysis, and probably the one you are most familiar with, is optimization and finding the best of something. You might be looking for the best route to travel, the best path to ride a bicycle, the best corridor to build a pipeline, or the best location to site a new store. Using multiple input variables or a set of decision criteria for finding the best locations and paths can

“If you don’t know where you are, you are lost. Understanding where is about putting the world in context. Where are you? What is around you? Very similar to when you were two years old, your journey of spatial analysis requires an understanding of how you fit into your geography. Understanding where includes geocoding your data, putting it on a map, and symbolizing it in ways that can help you visualize and understand your data.

“A blockchain is a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. It is a ledger that records transactions in a verifiable, permanent way.” “Geography is critically important to capture in a blockchain record, which is why we are now calling this a geoblockchain.” “Adding location to the blockchain would provide enhanced security and validation because the same
