Publicly Available IKONOS-2 Commercial Imagery

The USGS Commercial Data Purchases (UCDP) imagery collection is an archive of commercial remote sensing imagery from several different commercial vendors. The UCDP imagery is located at the Earth Resources Observation & Science (EROS) Center. This collection of imagery supports the Commercial Remote Sensing Space Policy (CRSSP).

The overall goal of the UCDP imagery collection is to provide data to qualified users, primarily federal agencies at no cost or at a nominal cost. Limitations on which users have access to use/purchase copies of the imagery are based on vendor licensing for individual images. Users are allowed to search all UCDP imagery in the archive, but are restricted to only ordering properly licensed images. Users have the option to purchase imagery license upgrades for imagery not currently licensed appropriately for their federal agency. The Commercial Remote Sensing Data Contracts (CRSDC), available through the USGS, handles the imagery license upgrades. The imagery license upgrades enable federal users to purchase and use a copy of the imagery at a nominal fee.

Copies of the current imagery can be downloaded/purchased from EarthExplorer. Users can not specify processing parameters for the imagery. (e.g. if an IKONOS image was originally purchased from Space Imaging as a "Standard Ortho" product, UTM projection, WGS84 Datum, and GeoTiff format, those are the only parameters available for that image.)

Current USGS Commercial Data Purchases (UCDP) imagery includes IKONOS imagery from Space Imaging, QuickBird Imagery from DigitalGlobe and OrbView imagery from ORBIMAGE.

美国地质调查局（USGS）商业数据采购（UCDP）影像数据集，是一个收录多家商业供应商提供的商业遥感影像的存档库。UCDP影像存储于地球资源观测与科学（EROS）中心。该影像数据集旨在支撑《商业遥感空间政策》（CRSSP）的实施。

UCDP影像数据集的总体目标是为符合资质的用户（主要为联邦政府机构）免费或以极低成本提供数据服务。用户是否有权限使用或采购影像副本，需以单张影像对应的供应商授权许可为准。用户可检索存档库中的全部UCDP影像，但仅能订购持有有效授权许可的影像。若当前影像的授权许可不符合其所在联邦机构的使用需求，用户可申请采购影像授权升级服务。可通过美国地质调查局（USGS）获取的《商业遥感数据合同》（CRSDC）负责处理影像授权升级相关事宜。通过影像授权升级，联邦用户可支付少量费用后采购并使用该影像副本。

当前可通过EarthExplorer平台下载或采购影像副本。用户无法自定义影像的处理参数（例如：若某IKONOS影像最初由Space Imaging以“标准正射”产品形式采购，其采用UTM投影、WGS84基准面及GeoTiff格式，则该影像仅支持使用上述固定参数）。

当前UCDP影像数据集收录的影像包括Space Imaging提供的IKONOS影像、DigitalGlobe提供的QuickBird影像，以及ORBIMAGE提供的OrbView影像。
