- Unlock the Power of Spatial Analysis using CARTO and Python
- CARTO Webinar — Internet 2019-09-25
Learn how to integrate spatial data and analysis to your data science models using CARTOframes—a Python package that allows data scientists to seamlessly integrate CARTO maps, data, and analysis into their current environment.

We have recently launched a new CARTOframes version packed with new functionality to build powerful end-to-end spatial data science workflows.

In this webinar, Andy Eschbacher (Data Scientist) and César Monteserín (Product Manager) show how you can power your spatial data science journey with CARTOframes:

- Creating interactive visualizations straight out of Jupyter notebooks
- Enriching your data with best-in-class data streams
- Analyzing your data and getting insights using your own libraries, functions, and workflows
- Uploading and sharing your maps

We go over CARTOframes new functionality and real-life examples.

- Adding Spatial Structure and Data to Machine Learning Models
- Data Council — San Francisco, CA, USA 2019-04-17
- Spatial data science uses many of the
same techniques and algorithm as traditional data science, but the
spatial component can add a large amount of additional information by
combining with other sources at the same location (e.g., census,
geolocated tweets), using realtime routing services, or using the
spatial structure of the distribution of the data.

In this talk, I will highlight work we have done with constraint-based clustering, probabilistic principal component analysis, and vanilla random forest that take special advantage of the spatial part of the data. I will further show how we build models from a variety of sources, including mobility data, points of interest, and accurate routing data.

For example, using the Python package CVXOPT, we solved a linear optimization problem that optimally distributes an asset from a source to a drain according to the road network and constraints that the drains cannot be over capacity, occasionally have fixed assignments, and all the asset has to be moved. - Maps & Machine Learning: Best Practices for Great Cartography in Data Science

- Making good maps in data science is
hard. Maps are another form of data visualization with its own set of
design principles to bring out the story in the data. Data scientists
need for maps varies, but a very common use case is to quickly generate a
data visualization iteratively to better understand model outputs,
spatial variations in the data, and more.

In this mini-tutorial, I will cover best practices for data scientists needing maps -- ideas pulled from cartography and honed over the years working in the intersection of open source GIS and data science. Using open source tools, I will show how to make patterns more apparent, how to build interactive maps so that it is easier to explore data on larger and smaller scales, and list some cartographic tips and tricks. The goal is that data viz with maps will be made easier so that you can think about your data science problems instead of worrying about visualizing data on a map. - Best Practices for Spatial Data Science using CARTO and Python

- Learn how you can combine CARTO and Python for spatial data science from the comfort of your own Jupyter notebook. In this technical webinar, Andy Eschbacher (Senior Data Scientist at CARTO) and Joe Pringle (VP - North America at CARTO) will show how to apply CARTOframes and CARTO's Python SDK to build powerful end-to-end spatial data science workflows.

- The spatial part of a dataset gives
more than just a lat/long. It allows you to thread a needle through any
other spatial dataset that exists at that location: census, GPS tracks,
data from a municipality's open data portal, and so much more. The
spatial part is a key to a multidimensional world.

Augmenting your spatial data is only one piece, though. Once you know a location, you can use the measurements at the locations around you by appealing to Tobler's First Law of geography: "Everything is related to everything else, but near things are more related than distance things." Using this, statistics of geography allow you to find spatial correlations (Moran's I), calculate spatial regression (geographically weighted regression), and uncover spatial outliers (Getis-Ord's G*). At CARTO we're building these powerful techniques into an API (https://github.com/CartoDB/crankshaft) where data scientists can extract more value from his/her spatial data. Combined with the data augmentation process that we call the Data Observatory (https://carto.com/data-observatory), data scientists are freer and more enabled to explore their data in the context of the world. - Teaching New Cartography, with Rich Donohue
