Draw On Maps And Make Them Easily

This map view includes an interactive timeline management which lets you view the map for different dates in world history. The small black dots on the map represent historic place-names, which seem as you zoom in on the map. Chronas is another interactive map which aims to offer a view of historical events across the globe through time. This interactive map visualizes Wikipedia entries by date and by location and also shows nation borders for various dates in historical past.


A World Map is a representation of all continents and international locations on the planet. Looking at a world map tells us the depth and shallowness of our data about our world, on the identical time. We have been utilizing MapPress for years and discover it straightforward to make use of and a great addition to our web site. The developer also offers great support and put out and replace in lower than 24 hours when a problem was found. We found that their documentation made it easy to install and simple to add maps to our pages, even a novice had no problems.

Personalizing Your Map

PurpleAir sensors, with out the utilization of the EPA correction equation, measure the same tendencies in PM2.5 concentrations as collocated monitors, however they tend to overestimate the PM2.5 mass concentrations. For the sensor knowledge used within the Fire and Smoke Map, EPA has utilized an extended U.S.-wide correction equation, developed by EPA scientists, that reduces the bias in the sensor knowledge correcting for the overestimation. The location at present set is shown as a flashing blue circle. For the Fire and Smoke Map, we quality control sensor data to remove questionable information factors and apply a correction equation to take away bias in the sensor information before showing sensor data on the map.

Take Snapshot Of Map

Use colour ramps, that are designed by experts in color concept; map symbols that look good at any scale; and symbology that’s instantly tied to the distribution of your data. Each of those interconnected settings intelligently guides you to create lovely maps you can confidently share along with your audience. Expedite your journey to stunning and informative maps with sensible mapping. Intelligent defaults present an excellent start line for visualizing and exploring your data.

Measurement technology — Sensors, together with the PurpleAir sensor, usually measure particles utilizing mild scatter, function at lower flowrates, and don’t dry the sampled particles like everlasting and short-term displays. This can lead to inaccuracies compared to permanent and momentary screens. To decrease the chance that small fluctuations in air quality are mis-interpreted as an growing or reducing development, we use a ten percent “buffer” round every NowCast AQI breakpoint. This means we do not label a development as rising or reducing till knowledge show PM2.5 concentrations are 10 p.c larger than the focus breakpoint between two NowCast AQI classes. The general Fire and Smoke Map shows hourly particle pollution (PM2.5) levels in the color-coded categories of the Air Quality Index .
