Inland Water levels… Globally. Copernicus did it again!

The Water Observatory is an Earth-observation-based solution that provides reliable and timely information about surface water levels of waterbodies across the globe. All observations are provided and can be explored interactively via the Water Observatory Dashboard or via RESTful API. The Water Observatory provides a valuable service to local authorities, governmental agencies, natural parks and reserves, agricultural ministries and agencies, stakeholders in food and energy production, and citizens alike.

Google Earth Engine and Dynamic World

Let me please introduce you this “new” LULC source I have come across with recently. The potential of this 10m “clutter” source is being able to acquire data from a few days ago instead of using outdated “very old” 2020 vintage datasets. I know if these days something 2020 is very old then myself, born in 1972 then i’m older than the riverside, older than peeing in a wall, even older than Methuselah. Yes, that’s the way it is nowadays.

Google Earth Engine is a geospatial processing service where you can perform geospatial processing at scale, powered by Google Cloud Platform. The purpose of Earth Engine is to:

Provide an interactive platform for geospatial algorithm development at scale
Enable high-impact, data-driven science
Make substantive progress on global challenges that involve large geospatial datasets

Ship Monitoring from space: SUEZ

Below you can see the example timelapse of Suez Canal ship traffic, made with a Sentinel-1 custom composite visualization. You can observe the moving ships as time passes.
Sentinel-1 is a pair of European radar imaging (SAR) satellites launched in 2014 and 2016. Its 6 days revisit cycle and ability to observe through clouds makes it perfect for sea and land monitoring, emergency response due to environmental disasters, and economic applications. This dataset represents the global Sentinel-1 GRD archive, from beginning to the present, converted to cloud-optimized GeoTIFF format.

Sentinel-hub: Highlighting value differences in deserts! (not only!)

This Sentinel-2 aesthetic script can be used to produce beautiful, neon looking results over urban and dry areas. The script is especially useful to highlight value differences in deserts. It’s essentially an RGB composite, with a B12 and B04 difference (which does a good job at displaying certain desert features, like dunes) in the red,Continue reading “Sentinel-hub: Highlighting value differences in deserts!

Visualising Wind from a GRIB Mesh Layer in QGIS and Create an Animated GIF

For a brief introduction into this new GRIB Mesh format (new to me) I followed step by step this tutorial bellow I had found in Hans Van der Kwast YouTube channel, it happened to be very good source and I finally made it (see below). The idea was analysing the winds during a Storm in the Netherlands (this storm was actually the 14th of March 2022 but I analyzed the 15th, no impact on the tutorial whatsoever but please note this point).

Wildfires in the sub-Saharan region

This image, acquired by one of the Copernicus Sentinel-2 on 8 February 2022, shows ongoing wildfires in the Boma National Park in South Sudan. Fires are common at this time of year in the sub-Saharan region.

Homicidio doloso en Ciudad de México 2013-2015

Recibí este link por Facebook hace un rato (Gracias Paco!)… https://hoyodecrimen.com/mapa#/19.4052/-99.0987/12 y me dediqué unos minutos a analizar un hecho puntual, el homicidio doloso, en un periodo concreto de tiempo, de 2013 a 2015. Veamos la previsualización de todos los homicidios ocurridos en 2013 en CARTO. El autor de la página llamada CRIMEN POR TUContinue reading “Homicidio doloso en Ciudad de México 2013-2015”

Running en Nantes

Cada vez que corría por esta maravillosa ciudad, lo grababa con la aplicación Runkeeper, así que he superpuesto todas las ocasiones para ver dónde exactamente se concentran las rutas que más he usado y las zonas por las que he pasado más veces. Esto es lo mal de concentrar en la misma persona alguien alContinue reading “Running en Nantes”

Crea una cuenta Incorpora tus datos o tómalos de la galería Selecciona en modo datos la columna que quieres simbolizar/visualizar Conviértela en NUMBER si estuviera en STRING Selecciona en modo mapaContinue reading “Jugando con CartoDB”

Change detection – Detección de cambios en polígonos

THE IDEA: DEMONSTRATING HOW DYNAMIC A CITY IS, THUS HOW IMPORTANT IS HAVING AN UPDATED DATASET THE FACTS: THE CITY OF BOGOTÁ IN COLOMBIA 2012-2014 Overall growth rate: -0.12% ONLY HAVING INTO ACCOUNT THE DIFFERENCE OF BUILDINGS CAPTURED BETWEEN 2012 AND 2014 (We can do this because we have used the same data capture model in both years) (DeContinue reading “Change detection – Detección de cambios en polígonos”
