My passion is conservation. I was an archaeologist for eight years before I got into my second career, GIS. I would be out on sites surveying for archeology and come across mass developments where they'd bulldoze everything in the way of a pipeline. It was crushing me.
It's not really about the technologies we use, its about understanding the principles behind the technologies, and where and when to apply them. Spatial thinking is the key skill, we don't need to master every new GIS tools, just knowing that they exist might be enough.
For most people, when they think aboutthe relationship between GIS and COVID-19, the obvious solution is tracking data. At the highest level, if there is any spatial relationship between where we are in our societies, where we go, who we interact with, and spread the disease, our measurements, thenour policy tools must also have a geospatial component to capture that effect.It's not a question of whether spatial data and spatial analysis matter for COVID-19. The problem is understanding what tools exactly can be used for specific insights and decisions.
GPUs have orders of magnitude more processors. However, they're not as general-purpose as CPUs. They do discrete bits of work that are more or less the same weight. If you can figure out how to subdivide a problem into 20,000 pieces of equal weight, they will do it in less than a snap of a finger.
It's adiscrete system, breaking up the world into discrete cells. Every position in the world has a cell identifier associated with it. It's global. In H3, we subdivide each cell into seven smaller cells. If you try to draw that out, you’ll realize it doesn't fit right. We had to make some compromises ...
Google Cloud’senterprise data warehouse. It’s an immensely scalable and quick data storage and processing product that got a geospatial facelift a couple of years ago. Users interact with BigQuery with standard SQL verbs. It feels like a relational database except you can have relations and tables that are petabytes big ̶ but to the user, it’s still just a simple case of typing in SQL.
We now live in an age where almost everything is customizable and can be adapted to our individuality. In previous eras, maps were physical documents. If you went hiking and you took a one-to-one map with you, where would you even put it? It wouldn't be helpful. In the digital realm, we capture the information from smartphones, from IoT devices, intelligent cars driving around, satellites, and building sensors. We put these into place and have a perfectly clear picture of the world in its digital format—this is your digital one-to-one map.
Segmenting data and audiences is really big at the moment, its about getting the right message to the right person at the right time. Geospatial is a big part of that, it's about putting your data in context.
Everything happens at a location and at a specific time. Why have GIS standards ignored the temporal aspect of data, why don't we have the same kind of functionality for spatial-temporal data that we have for spatial data? Anita Graser, the creator of the time manager plugin for QGIS answers these questions.
Property is surrounded by a legal space that the government defined and sectioned off to the owner with a street address for tax purposes. It’s a polygon, rectangle, or square space. A host of other information is connected to that parcel, such as when it was first subdivided, is there a structure on it, and does it have utility hookups? What are the permissions, zoning, and taxes owed on it?
Jupyter Notebooksare an interface for combining code, documentation, and data access. Previously, your data was held in one location. You coded somewhere else and output it to a different folder which you opened to see what your code did. A notebook is a single place where you combine code, workflow, documentation, and the results.
Remote sensing with a difference. That’s what Ellen Christopherson, CEO and founder ofclearGrid, is here to talk about. Their unique way of collecting radio frequency (RF) data makes them a valuable partner for utility and energy companies that do any type of meter readings and billings. Ellen’s background in aviation engineering gives her an edge to see how technology can deliver efficiency in this space.
Indoor positioning and navigation are still done on a case by case bases and generally only offer sub-meter accuracy. But what if you had millimeter accuracy? what problems could you solve or use cases could you dream up?
A digital twin is a digital replica or model of a living or non-living physical object. Geospatial and CAD data often provide the physical context for these objects but no digital twin would be complete without different real-time or near real-time data streams.
Anita Graser is a legendary open-source geospatial Python expert. With her extensive knowledge of the subject, she is here to convince us of why Python is a great language and how we can all get started learning it. Stick around to see the benefits and learn why Python may or may not be an option for your GIS project.

GIStechnology is underutilized. There is a huge opportunity for professionals in the geospatial industry to be leaders and not just mapmakers. Cartography is an important part of what GIS professionals do but it does not have to be the only thining that they do.
Historically, CAD was used to draw buildings and facilities. These systems were never meant to store complex attribution we take for granted in the GIS world today. This geospatial podcast episode explores the differences between Computer aided-design and geographic information systems.
The Mars Rover Project. Autonomous robots monitoring substations. How is this all relevant to the geospatial community? Scott Nowicki is happy to clarify. He explains the technology that enables robots to integrate detailed maps, orientate, and move around their environments as they go on their daily business and build detailed change detection maps for substations and facilities management. But the question is, can they and do they truly add value to operations where human presence is difficult or unnecessary?
