Base Packages We offer a variety of base survey and mapping packages.

Our products fall into three categories:

I. Satellite Surveying

Complex projects require accurate survey data without disrupting ground operations. Project sites are often large or hard to access, making it slow or difficult to survey such sites by conventional means.

Our surveying products are suitable for earthworks construction, operating and developing mines, and tailings management.

II. Satellite Mapping

In early stages of a project, it is often necessary to obtain reliable topographical data over large areas (100s to 1000s of km²) in an efficient and economical manner. In these cases, ground controls frequently do not yet exist.

Our mapping products are suitable for exploration planning, geological targeting, logistical coordination, and more.

III. Alteration Mineral Mapping

Using data processing with spectral analysis, we can produce alteration mineral maps that distinguish between many key minerals.

Our alteration mineral maps are useful tools for exploration geologists.

Base Packages

PhotoSat has completed over 1,300 projects in more than 75 countries.

Recurring Survey Package The Recurring Survey Package delivers our engineering-quality surveys of a site automatically throughout the year. For active sites with tailings facilities or complex operations, this package is a practical way to obtain the data you need in a timely and consistent fashion.

Recurring Surveys can be used to establish monthly production quantities, monitor dyke construction, and monitor tailings placement. A database like this can also be used to resolve contract disputes, meet unforeseen survey requirements, or address other unexpected situations. Overall, it forms an updated database of relevant topographic data.

Some sites rely on the satellite archive, however the satellite archive does not guarantee that site-wide photos will exist at dates you may require. The Recurring Survey Package guarantees a site-wide survey record at regular intervals.

Timeline for DeliveryEvery project is unique. There are a number of outside factors that influence the total delivery time of a surveying or mapping order.

Phase 1: Obtaining Satellite PhotosFor new satellite photos, collection can be delayed by persistent cloud cover over the site, satellite production capacity, and a few other factors. Under ideal conditions, it usually takes ~5-7 business days to collect new satellite photos.

For archived satellite photos, it typically takes ~2-3 business days to conduct an archive search for a single survey or map order. If suitable photos exist, we may be able to use them.

Phase 2: Data ProcessingAfter we receive the satellite photos, data processing can begin. The majority of mine site surveys are around 50-70 km² in size. For these types of sites, most data processing times are:

• ~10 business days for a first-time survey• ~5-7 business days for repeat surveys

Other factors may increase data processing time, including:

• Add-on products (e.g. water body outlines)• Certain types or terrain and/or high numbers of ground features• Requests for extra file formats and/or thinned grid formats
