ISO/TS 19130:2010确定了确定遥感像素在图像坐标中的位置与其地理位置之间的关系所需的信息。它支持利用遥感图像。它定义了要与图像一起分发的元数据，以使用户能够根据观察确定地理位置。ISO/TS 19130:2010规定了可以提供支持地理定位的信息的几种方式。它可以被提供为具有严格构造物理传感器模型所必需的相关联的物理和几何信息的传感器描述。对于需要精确地理位置信息的情况，ISO/TS 19130:2010确定了用于严格构建物理传感器模型的数学公式，该模型将两个-三维图像空间到三维地面空间以及相关传播误差的计算。ISO/TS 19130:2010提供了三种类型的无源电光/红外（IR）传感器（框架式、推扫式和搅拌式）和有源微波传感系统【合成孔径雷达（SAR）】的详细信息。它提供了一个框架，通过该框架，这些传感器模型可以扩展到其他传感器类型。它可以被提供为真正的替代模型，使用其系数基于物理传感器模型的函数，使得它们提供用于精确地理定位的信息，包括误差的计算，与它们所替代的物理传感器模型一样精确。它可以被提供为对应模型，该对应模型基于一组地面控制点的地理位置与其图像坐标之间的观测关系来提供功能拟合。它可以被提供为一组地面控制点，其可以用于开发对应模型或细化物理传感器模型或真实替换模型。ISO/TS 19130:2010既没有规定用户如何获得地理位置数据，也没有规定用户生成的数据的格式或内容。

ISO/TS 19130:2010 identifies the information required to determine the relationship between the position of a remotely sensed pixel in image coordinates and its geoposition. It supports exploitation of remotely sensed images. It defines the metadata to be distributed with the image to enable user determination of geographic position from the observations.ISO/TS 19130:2010 specifies several ways in which information in support of geopositioning may be provided.

1. It may be provided as a sensor description with the associated physical and geometric information necessary to rigorously construct a Physical Sensor Model. For the case where precise geoposition information is needed, ISO/TS 19130:2010 identifies the mathematical formulae for rigorously constructing Physical Sensor Models that relate two-dimensional image space to three-dimensional ground space and the calculation of the associated propagated errors. ISO/TS 19130:2010 provides detailed information for three types of passive electro-optical/infrared (IR) sensors (frame, pushbroom and whiskbroom) and for an active microwave sensing system [Synthetic Aperture Radar (SAR)]. It provides a framework by which these sensor models can be extended to other sensor types.
2. It may be provided as a True Replacement Model, using functions whose coefficients are based on a Physical Sensor Model so that they provide information for precise geopositioning, including the calculation of errors, as precisely as the Physical Sensor Model they replace.
3. It may be provided as a Correspondence Model that provides a functional fitting based on observed relationships between the geopositions of a set of ground control points and their image coordinates.
4. It may be provided as a set of ground control points that can be used to develop a Correspondence Model or to refine a Physical Sensor Model or True Replacement Model.

ISO/TS 19130:2010 does not specify either how users derive geoposition data or the format or content of the data the users generate.
