(TS) Value: 134K Euros Country: Netherlands This tender concerns the oblique photographs. These oblique photographs are used in the exercise of various public tasks of the Client and the municipalities for which the Client purchases the photographs. This concerns various (current and future) tasks such as taxation, enforcement, licensing, mapping, legal procedures, implementation of basic registrations, mutation detection, et cetera.

(TS) Value: 134K Euros Country: Netherlands Lot 1 of this tender concerns the periodic delivery of digital stereo photos and ortho photos on the basis of these stereo aerial photographs. Various departments of the participating municipalities need a high-quality digital ortho photograph of their own municipal territory. Ortho photographs are required for, among other things: performing tasks in the context of the Environment Act, basic registrations within the context of the BAG and BGT, enforcement tasks, land transactions, civil engineering projects, etc. Initially, the contractor must collect stereo aerial photographs. This involves vertically reduced aerial photographs that have a certain overlap in the flight direction and in the transverse direction (longitudinal overlap 60% / transverse overlap 30%). This picture' s are taken using a special camera system on board an aircraft. Based on the stereo aerial photographs, the contractor must then prepare orthophotographs of the territory of the participating municipalities. In orthophotos, deviations caused by height differences in the terrain, lens distortion and the position of the aircraft have been corrected. The photographs are fitted into a coordinate system and can be represented as one large mosaic with the aid of a viewer, thus forming a photographic digital map of the municipal area in question. The aerial photos should be periodically replaced by more recent copies, so that stereo aerial photographs and orthophotos are constantly available to show the current situation on the spot. All contracting authorities taking part in the tender wish to receive digital stereo aerial photos and, on that basis, ortho-photos of their entire territory once a year for the duration of the agreement. For a more detailed description of lot 1, please refer to the Schedule of Requirements included in Appendix 2, part 'Specifications orthophotos'. Lot 2 concerns the delivery of high quality digital obliekfoto's. These are aerial photographs taken at a certain angle (45o) (therefore not vertical or perpendicular to the bottom), so that other details become visible than aerial photographs taken perpendicularly downwards. This photo too s are fitted into a coordinate system and can be displayed with the help of a viewer, whereby objects (for example: dwellings or housing extensions) can be looked up and viewed from different directions.

UK Concept of Operations Stakeholder Engagement

You may have heard occasional references to ‘Project Chatham’ over the past few months, either from Government communications regarding its Unmanned Aircraft System/Drone consultation, or via a direct input from one of the
project team.

The project is centred on the production of a single, nationally approved set of data which can portray to operators, manufacturers and organisations that offer support functions (such as mapping app providers), the necessary information about airspace within which flights of small unmanned aircraft are either restricted or prevented. The next part of the project involves the publication of a draft data set in AIXM 5.1 which we can offer to a small targeted audience as part of stakeholder engagement in order to receive feedback as to whether or not the intended data set is useable as part of our assessment of the next steps.

We have now reached this part of the project and would like to make use of your company in this process.

Please click below to fill out a questionnaire seeking
your views on the usability of the data set.

Support: See here for description of model. Or contact steven.hill@nats.co.uk

Conditions: Not for operational use, for test purposes only.


Note 1: The draft data set is not complete and should only be used for test purposes in order to provide a response to the questionnaire.

Note 2: For Developers – The Universal Unique Identifiers (UUID) will change prior to the data set being released into service.

Note 3: Ownership of an ATZ qualifies an aerodrome to be included in this current data set, therefore a small number of licensed civil Aerodromes are not included. This anomaly is expected to be resolved once the ANO amendment has been finalised.

Note 4: The material in this email should not be passed to other parties unless approved by the CAA.
