The most detailed tweet map ever

Mapbox have produced a map of over six billion tweets collected over the last few years. Each geolocated tweet is represented by a green dot. The below map is fully zoomable and interactive.
 

What makes this map different from other twitter maps is the sheer size of the dataset used  - 6,341,973,478 tweets! Time has also been taken to ensure sure the map looks good. Without careful fitlering of the data, unsightly and odd looking banding and splotching would appear on the map.

FIND's marine division, MarineFIND, and EOMAP partnership to produce easy access marine bathymetry data

Working together, EOMAP GmbH & Co KG and MarineFIND, the specialist marine data and service division of FIND Maps, have formed a partnership to offer easy access to coastal high resolution and global bathymetry.

Collecting nearshore zone bathymetry data has, until recently, been an expensive undertaking. However, advances in the processing of satellite imagery means that low-cost, accurate, high resolution bathymetry to a depth of 20m is now available. The EOMAP/MarineFIND partnership has developed a new method for easily distributing this data for preprocessed areas and allows the production of cost-effective custom datasets.

   

Satellite derived bathymetry from EOMAP and MarineFIND Dr Thomas Heege, CEO of EOMAP, said: “We’ve worked with MarineFIND on several recent projects and the partnership has delivered excellent results for our clients. Building on the work we’ve already done together, we can now deliver bathymetric and other marine data to many more clients worldwide.”

Jon Coleman, Marine Business Manager of MarineFIND, said: “MarineFIND.co.uk is already one of the industry’s leading GIS portals for marine data. Our expert developers have improved delivery mechanisms – allowing us to serve cost-effective high quality marine GIS data directly to client desktops via WMS technology.

 Nigel West, Consultant at ABPmer, said: “We’re very happy with the satellite derived bathymetry from EOMAP/MarineFIND. It has proved invaluable for the characterisation of shallow coastal areas in the Red Sea and Mediterranean Sea. In our areas of interest, satellite imagery showed shallow bathymetric features that were either inaccessible to survey vessels or beyond the remit of the original surveys. The data we received from MarineFIND showed good validation with our echo-sounder collected data.”

EOMAP is the leading commercial supplier of satellite-derived data for the marine environment. Core services include very high and medium resolution bathymetric surveys, as well as near real-time water quality monitoring. EOMAP holds a unique shallow water bathymetry database that is now available through MarineFIND. Other new products include:

• Water quality 
• Water depth 
• Seafloor/benthic mapping 
• Subsurface reflectance 

Since 2006, EOMAP has provided marine services to clients in the O&G, coastal engineering and environmental sectors. Applications of their large scale techniques include mapping benthic habitats and bathymetry for the Environmental Agency of Abu Dhabi and mapping the whole of the Great Barrier Reef. Recently, EOMAP launched a WaterQuality App to provide easy access to demo data for Australia (http://eoapp-au.eomap.com/). The aim of their latest partnership with MarineFIND is to extend the provision of easy access to usable, complex data.

Dr Thomas Heege, CEO of EOMAP, said: “MarineFIND is a unique portal for marine data and we’re happy that it now offers our competitively priced Satellite Derived Service”.

More accurate exporting and annotating with FIND Maps September 2014 update

FIND Maps now has the ability to create export areas and annotations more accurately by typing in exact values, such as centre points, radiuses and buffers. We've also added dynamic 'widescreen' map viewing.

Simpler and more accurate exports

• New easy-to-use step-by-step ordering
• Rectangle export: enter exact area size and corner coordinates
• Circle export: enter exact radius and centre coordinates
• Free-draw export: add a buffer

Key benefits: Save time and order exports more accurately.

Map annotation tool enhancements

• Enter exact rectangle dimensions and corner coordinates
• Enter exact circle radius and centre coordinates

Key benefits: Create more accurate annotations by typing in exact values.

Widescreen map viewing

• The map screen dynamically resizes to your web bowser window creating largest map screen possible

Key benefits: Make the most of your screen real estate with a large window to work on your mapping.

Video guide: Export OS MasterMap with findmaps.co.uk (DWG, DXF, SHP, TAB)

We have produced a video guide to exporting OS MasterMap in FIND Maps. This commonly undertaken task can be completed in about two minutes for a typical 4ha area.



FIND Maps offers flexible and efficient OS MasterMap exporting

Export with FIND Maps to:

• carefully define your export shape with three different types of 'cookie-cutter' tools (square, circle and editable nodes)
• export in both CAD and GIS formats (DXF, DWG, SHP, TAB)
• choose from one, two and three year licenses available for OS MasterMap
• view up to 15ha of MasterMap free per session while exporting.

Video guide: Create 1:1250 A4 Location Plans with findmaps.co.uk

We have produced a video guide to creating 1:1250 A4 Location Plans in FIND Maps. This commonly used feature can be done under 3 minutes using the findmaps.co.uk online mapping application.

FIND Maps offers flexible and efficient OS MasterMap printing and annotation. A range of different map scales can be selected, including 1:1250 and 1:2500. Also, a red-line property boundary can be added to the plot using the 'merge polygon' tool that enables you to quickly trace a property boundary.

Get a better looking map

The quality and style of maps is becoming increasingly important to many firms. When presenting maps to a client it’s especially important that they look clean and professional. This is essential for creating the right impression and increasing ‘production value’.

For example, boundary maps used in catalogues and listings by estate agents must be accurate and clear. As well as being useful and attractive, they must also complement the overall design of the document or website.

The ‘FIND Map’/OS MasterMap with a carefully developed theme for ease of interpretation and enhanced presentation

Styling is especially important when using OS MasterMap because it is a vector (data) product that must be styled in order to convert it to rasters for creating prints and images. When hundreds of different map elements need to be individually styled this can be a time consuming process.

FIND has carefully styled OS MasterMap to highlight property-related elements such as building outlines and to remove superfluous line work and text. This produces maps that are easier to interpret and are therefore ideal for inclusion in reports and catalogues.
