KMZ

KMZ is a variation of KML which stores the geospatial data within a ZIP archive.

OSM

The OpenStreetMap XML format lets you import data from the OpenStreetMap project, which includes things like roads, houses, and points of interest.

GeoTIFF

GeoTIFF is a format for spatial raster data, like images from satellites or airplanes. Placemark supports importing the bounding box from a GeoTIFF image, and there are many other tools to process GeoTIFF images more completely.

FlatGeobuf

A new, efficient format for storing geospatial data that's similar to GeoJSON but produces smaller files and can be useful for some cloud computing challenges.

Excel

Placemark's support for the XLS and XLSX spreadsheet formats

Shapefile

The shapefile is an old, popular, and limited file format that Placemark supports the import and export of.

GTFS

A geospatial format specialized for public transit.

CSV

A text-based file format that's popular as a spreadsheet export.

WKT

A text-based format that doesn't have the ability to contain attributes or metadata.

TopoJSON

An extension of GeoJSON that encodes topology in order to save space.

TCX

A format for sports data popular as an export from running watches and bike computers.

Raster Data

Pixel-oriented data, often with many color and spectrum bands.

Polyline

A simple, compact data format that just encodes lines.

KML

Google Earth's native format and a popular export from consumer mapping tools.

GeoJSONL

A version of the GeoJSON format that is optimized for big datasets.

EXIF

A kind of geospatial data that's included in some JPEG photos to keep track of where they were taken.

GeoJSON

A popular JSON-based geospatial data format.

๐Ÿ“– Guides

Joining data

Joining lets you combine geospatial and non-geospatial data, thus multiplying the different datasets you can work with in Placemark.

Winding order

An option to export GeoJSON from Placemark that is compatible with the d3-geo module

Rich text

How to work with rich text properties in your data and in external applications.

Properties

Properties are part of what makes geospatial data so powerful: features can contain data, not just shapes.

Importing addresses

Importing map data from addresses in CSV or Excel files is really powerful, but address are amongst the trickiest kinds of data. Important notes for you to go forward.

Simplestyle

Simplestyle is a specification that lets you control how features are displayed on the map directly, by using properties and literal values for colors.

IDs

Features can have two IDs: your IDs and System IDs. You can use IDs in the REST API, imports, and exports to identify features.

System requirements

Details on what browser and configuration is required to make maps in Placemark.

Placemark REST API

A read-only API that lets you use your data in Placemark from web maps and any application that can access URLs and use GeoJSON data.

Collaborating on maps

How to work together on a team, editing maps at the same time.

Forms

How forms simplify the way you can edit map data in Placemark.

Visualization

The state of our support for interactive, dynamic map visualizations.

Geometry support

About the types of geometries that Placemark supports - including Point, LineString, and Polygon.

ZIP Codes

The US's ZIP Codes are a way of roughly grouping addresses. Placemark supports importing them when they're included in a CSV file.

Comparisons

How Placemark compares to other tools like QGIS, ArcGIS, and OSM.

Drawing

How you can draw, edit, and manage the shapes and geometries that make up geospatial data.

Importing

Pulling text, files, and API data onto the map.
