Some clients combine Keyline consultations with a holiday at Surfers Paradise on Queensland's Gold Coast where Keyline Designs is based. A consultation may start with an initial assessment , of the development potential. An initial Keyline assessment of topographic map may take as little as an hour. Further assessment of the supplied maps will result in a preliminary development proposal . The accuracy of these figures depends upon the precision, scale and contour interval of the topographic maps used.
Various factors influence the time required to produce a preliminary development proposal.
A Government topographic map at a scale of 1 in 25,000 showing contours at 5 metres is a suitable map upon which to base either an initial assessment or preliminary development proposal. Smaller scale maps hide options and are less precise. However even maps at a scale of 1 in 100,000 with a contour interval of twenty metres can provide very useful information and be quite indicative of the general potential of the landscape. Keyline Mapping Service Larger scale maps with closer contour intervals are preferable for planning. Keyline Designs Mapping Service can coordinate the production of true to scale, contoured aerial photo-maps.
