There is no evidence that the adoption of the technology by 
commercial survey companies is going to slow in the next 12 - 
18 months. Unlike 1997, when a significant increase in 
installed systems the year earlier was followed by a drop in 
orders, 2000 looks set to follow-up on 1999’ level of deliveries 
with continued gains. With 10 systems already confirmed for 
delivery within the first six months, the total order book for the 
first half of 2000 is ahead of the year-earlier pace. Initial 
projections indicate that annual deliveries will remain at or 
exceed the 1999 level. 
It is also useful to look at the breakdown of installed 
instruments by manufacturer, with proprietary systems as a 
separate category. Table 4 presents this breakdown as of 
January 1, 2000. 
  
  
  
Manufacturer #instruments % base 
Azimuth 2 5% 
Optech 17 45% 
TopEye 7 18% 
Proprietary * 12 32% 
Total 38 100% 
  
* Includes 3 instruments that are based on a proprietary design 
of Azimuth’s OTS instrument. 
Table 4. Installed Instrument Base by Manufacturer 
Since 1995, the commercial off-the-shelf manufacturers have 
captured 68% of the instrument market. Optech has established 
itself as the market leader with 65% of the OTS market. If the 
proprietary sensors that are based either on Azimuth subsystems 
or proprietary designs of their standard sensor are included as 
OTS systems instead, then the commercial instrument 
manufacturers have 76% of the installed base. The subtotal 
reported in Table 4 for proprietary instruments includes a 
number of legacy instruments that were already built or in 
development prior to the widespread availability of commercial 
off-the-shelf systems. It is not clear if the organizations 
operating these proprietary sensors would replace their systems 
with OTS instruments or continue their own proprietary 
development if they need to expand their instrument base. 
    
  
   
      
   
  
  
   
    
   
    
  
  
  
   
  
   
   
  
  
   
   
     
   
   
    
    
    
   
    
    
    
    
   
    
  
   
   
    
  
  
  
   
    
    
  
   
     
   
   
   
   
   
   
   
  
    
    
    
     
    
   
   
    
Since January 1998, only 2396 (6 of 26) of systems delivered to 
the field have been proprietary builds. Further evidence of a 
shift away from custom-built designs can be seen in the fact 
several owners of previously proprietary designs (Nortech, 
TerraPoint, TopoSys) have recently started to formally or 
informally offer their customized systems for sale or lease. This 
change in business strategy for companies previously focused 
exclusively on providing survey services through proprietary 
technology can be attributed in part to the successful emergence 
of dedicated instrument manufacturers. It is becoming harder 
for survey companies to leverage the capital investment 
required to develop a proprietary instrument into a 
corresponding increase in their share of the survey market. 
Access to OTS instruments with similar, or in some cases 
enhanced, functionality is readily available to their competition, 
reducing the competitive advantage for survey companies who 
design and build their own proprietary instruments. A 
proprietary development program also requires a survey 
organization to develop skills which are not synchronized with 
their survey business, while on-going support and maintenance 
for proprietary systems can divert staff and resources away from 
the core business. It can be anticipated that as more OTS 
instruments are deployed, there will be a further reduction in 
the percentage of custom-built systems operating in the market, 
although the actual number of proprietary instruments should 
continue to increase slightly. The fact there is still on-going 
development and deployment of proprietary systems with 
essentially the same functionality as OTS instruments is 
evidence that the capital costs of OTS instruments are still high 
enough to act as a barrier to entry for many survey companies. 
The capital investment to acquire a commercial OTS sensor still 
makes even the relatively large development costs of a 
proprietary sensor attractive to some companies. From this, it 
can be concluded that there must be some price-point flexibility 
on OTS instruments if the custom market is to be fully co-opted 
by the dedicated instrument manufacturers. Regardless of any 
future price reductions, custom-built systems will remain 
attractive for those organizations that can leverage existing 
laser/lidar expertise during their design process or for those 
organizations that require advanced functionality not yet 
offered by OTS systems. 
The geographic distribution of currently installed instruments is 
presented in Table 5. The distribution is heavily weighted 
towards North America and Europe. However, it should be 
noted that many of the current commercial operators have 
international operations, through either subsidiaries or strategic 
partners. Consequently, airborne laser surveys are being 
undertaken in most regions of the globe. In can be speculated 
that part of the continued growth in the installed instrument 
base will address current inefficiencies in delivering laser 
altimetry services to a global market without a regionally 
balanced base of sensors. Based on the breakdown of booked 
orders, North America and Europe will continue to experience 
the largest growth in available instrument base over the next 
12-18 months. However, several of the instruments in the 
queue are likely intended to address international operations of 
these firms and may be based outside Europe or North America.
