Mapping Toolbox には、カスタマイズした 2D および 3D の地図表示を生成するための可視化関数とアプリが用意されています。単純なものから高度なものまで、用途に合わせた地図表示の調整が可能です。スケールが異なるラスターデータセットとベクトルデータセットも、同じ表示内で簡単に結合することができます。たとえば、解像度や対象領域に関係なく、画像とデータグリッドを正しい位置に表示し、その上にベクトル地図の機能を重ねることが可能です。

このツールボックスの可視化関数を使用して、次のような処理が可能です。

• ラスターデータとベクトルデータを使用した 2D 地図表示を作成する
• ライティング、シェーディング、視点をカスタマイズした 3D 地図表示を作成する
• ラスターおよび位置情報グリッドデータから等高線図を作成する
• テーマ別の地図、3D 表面のドレープ画像、表示地図を画像として作成する

Create 3D Map Displays

Mapping Toolbox produces customizable 3D map displays. You can display flight trajectories over high-zoom-level basemaps, GPS data over terrain, or line-of-sight visualizations.

Maps in MATLAB

MATLAB^® provides geographic axes and charts for visualizing data that include geographic locations (latitude and longitude) on a variety of basemaps. You can plot lines between two locations, plot specific locations with markers, use location markers that vary in size with a related value (like population), and visualize the density of locations. With Mapping Toolbox, you can customize the basemap by specifying a URL string.

Select Basemaps

Basemaps are reference maps on which you can overlay vector and raster geographic data. They are useful for providing context for the data or analysis represented within the map display.

For web maps, geographic globes, and geographic axes, you can select from a number of built-in basemaps, including high-resolution satellite imagery, topographic features, landcover, and several styles of street maps. You can also add custom basemaps to the list of available options by specifying a URL string.

Geometric Geodesy

With geometric geodesy features in Mapping Toolbox, you can perform geodetic calculations that account for the curvature of Earth and other planetary bodies. You can find the surface area of arbitrary polygons or quadrangles on spheres and ellipsoids, calculate the intersections of geometric objects, and compute the distance between points on a sphere or ellipsoid.

Map Projections

Mapping Toolbox contains more than 65 of the most popular and important map projections for displaying the curved surface of planetary bodies on a 2D map display. They include equal-area, equidistant, conformal, and hybrid projections in the cylindrical, conic, and azimuthal classes. Many projections support both spherical and ellipsoidal models of Earth and other bodies.

3D Coordinate Transformations

Mapping Toolbox provides common 3D coordinate system transformations required when combining data from multiple sources. You can perform 3D geometric computations in the near-earth environment and transform point locations between 3D geodetic, geocentric, local east-north-up (ENU), local north-east-down (NED), and local spherical systems.
