Using Lasers To Talk To Satellites

The MapScaping Podcast - GIS, Geospatial, Remote... ·

2023/06/14

How do we get data from a satellite down to Earth? How do we task a satellite? Today the answer is likely to be via radios and a system of downlink sites or ground stations. As the satellites pass overhead or within “line of sight” data can be sent via radio from the satellite to the receiver on the ground. If you don’t want to wait until the satellite can see the ground station, you can send your data to a geostationary satellite that can always see a ground station and let it send the data back

From Pixels to Patterns: AI in Spatial Analysis

2023/06/07

There is a general understanding that it is becoming increasingly difficult to extract meaning from all the data we are collecting without using AI. But what is AI, and how did we end up in a situation where it is identifying wolves from dogs based on the presence of snow in the background of images? What does this mean for spatial analysis using tabular data? What is explainability? This is not a "how-to" do spatial analysis using an AI episode, it is an overview of AI in spatial

Big Data In The Browser

So why would anyone want to put alot of data into a browser? Well, for a lot of the same reasons that edge computing and distributed computing have become so popular. You get the data a lot closer to the user and you don’t have to pay for the compute ;) … this sounds great but as I found out during this conversation it's not as easy as it might seem! There are a lot of trade-offs that need to be evaluated when moving data and analytics to the client. Nick Rabinowitz Senior Staff Software

I am sure you have heard of ChatGPT by now so the hope of this episode is to give you some more context about what is it built on and how it works. To do that I invited Daniel Whitneck back on the podcast You can connect with Daniel here https://datadan.io/ and listen to his previous episode here: https://mapscaping.com/podcast/an-introduction-to-artificial-intelligence/ This is perhaps the quote for the episode that I have spent the most time thinking about "We always thought AI would be

Computer vision is a field of artificial intelligence (AI) that enables computers and systems to derive meaningful information from digital images. You might think that this is exactly what we are doing in earth observation but there are a few important differences between computer vision and what some people refer to as GeoAI. This week Jordi inglada is going to help you understand what those differences are and why it's not always possible to use Computer vision techniques in the field of

Data is what data does - more about that later on ;) This episode focuses on designing for privacy, how do we create value from location data without sacrificing personal privacy? Well, you might start by adhering to the Enhanced Standards For Precise Location Information which means that information about sensitive places like churches, hospitals, military bases, and LGBTQ+ spaces isn't misused or sold. Plus, they protect our exact location from being shared with law enforcement or bounty

Hyperspectral vs Multispectral

2023/04/13

When comparing multispectral and hyperspectral data it is not simply a case of “more data more better”! With hyperspectral you have “The curse of Dimensionality” but you also get more flexibility to pick exactly what bands you want to use! With multispectral you have less noise but you also have less data! This episode is designed to be a beginner's guide to the differences between hyperspectral and multispectral satellite data.

Foursquare uses a mixture of crowd source and data conflation to maintain a database of 205 million places ... and it's not easy! Each phone might see the world slightly differently in terms of location accuracies and crowdsourcing data means that people "check-in" at different locations.

Protomaps is a serverless system for planet-scale maps, it's an umbrella project consisting of a few different components one of which is PMtiles. PMtiles is “Cloud Optimise Geotiff” for web mapping, what this means is that you can build a base map and host it without the need for a server! PMtiles is a single file that you can access via HTTP range requests in the same way that you can access data within a Cloud Optimised Geotiff with the important difference that PMtiles can also contain vector

2023/01/25

This episode covers a wide range of topics from the role of geospatial in systems thinking - representing natural systems in location systems and how we can apply the technology behind virtual worlds to the real world. During this conversation, it became clear to me that technology should be used in service of culture and not the other way around. I think in terms of geospatial we have an interesting opportunity to have an outsized impact if we can just figure out how to market it! I often think
